Earlier today I came across a Reddit comment with a link to an Instagram post. The link had ?igsh= at the end.
When I clicked on the link, I got this popup. It had a name and profile photo that was different from that of the post being shared.

I avoid link trackers. However, I did not realize it was this bad.
To my knowledge, TikTok does the same thing and lists the name of the person that shared the link. Assuming this increases engagement, any website could enable such a feature, even on old links that you shared in the past.
You should manually remove any trackers before sharing, or use an app for it.
I tend to manually strip out anything random hash-looking from URLs. Not so much because I'm worried about identity being exposed, but because it just encourages data-mining and figuring out what causes people to post links places.
There's some open-source app I recall on Android in F-Droid that will do this for a set of known sites, "Link Cleaner" or something.

"Leon -- URL Cleaner". I assume that this is an allusion to the movie.
I also strip off the extension that the Wikipedia app adds to indicate that Wikipedia links are from the app.
I also strip off "m." leading URLs, like "m.wikipedia.org", since that, by convention, forces desktop users to see a mobile version of a site, which is not normally what they want, whereas a non-.m link will still show the mobile site to mobile users.
Generally anything that comes after a questionmark in a URL can be safely stripped out, though not always. The random string of characters you get after a youtu.be link is tracking, the ?t=123 is a timestamp.
YouTube has an even better example of it being problematic to strip the parameters. The original video links look like this:
https://www.youtube.com/watch?v=dQw4w9WgXcQ
The thing is, the stuff after the question mark isn't inherently bad, we just have the convention that the path (/watch) should identify a static resource on the server, whereas the stuff after the question mark is more variable or user-specific.
But YouTube is older than that convention. If YouTube got built today, that URL would look more like this:
https://www.youtube.com/watch/dQw4w9WgXcQ
On the other hand, the URL of a specific search result page would still look the same, even with today's conventions, because it doesn't identify a static resource:
Edit: the way it works, is that you set it up as your default browser. Then, whenever you hit a link, it will open up URLCheck first, and you'll get to decide what to do with the link, strip away query parameters, and which app to open the link with.
Yeah I have a habit of doing this and then testing the link to find the smallest possible version. Mostly because I find it annoying when I want to text a link to someone and it takes up an entire page of the chat.
Leon is great. I try to remember to use it anytime I share a link. As a result, I have found that that some links are just the base url plus a UUID (e.g. mycoolshoppingsite.com/GAJEBKT), so you can't strip out the tracking without breaking the link entirely.
Note that a TikTok link is un-cleanable. It will always trace back to you. Do not ever share TikTok links unless you're willing to expose your identity to the person you're sharing with.
It would only show the info relating to the account though, right? I don't share my Instagram because I can't figure out how to disconnect it from my Facebook (plus it doesn't embed on discord - very rude), but I don't use my real info for any of my other accounts.
While retaining the same product and removes your fingerprinting data.
This also applies for things like youtube, amazon, social media, etc. I have the cleanurls extension on firefox, yet it doesn't do a good job at removing this stuff, so I often have to manually do it before sharing links.
Mind that just removing everything after the question mark can break the link, because these parameters can also do useful things.
For example, if you use the search functionality on a webpage, you'll typically be redirected onto a URL with a parameter containing your search query.
And Firefox also has this tracking parameter removal built-in these days. In the right-click menu, you can select "Copy Link Without Site Tracking".
I cannot say, though, if this works better than CleanURLs. Because these parameters can do useful things, it's tricky to automatically remove them without breaking links.
The problem is that these parameters can also do useful things, i.e. removing them might break the link. There's no inherent criteria to determine whether a parameter is used for tracking or not.
The way these extensions or Firefox' built-in feature works, is that they check for 'well-known' parameters. For example, lots of URLs contain parameters starting with utm_, which is from Google Analytics: https://en.wikipedia.org/wiki/UTM_parameters
As such, it's for example unlikely that someone would build a website which uses a parameter utm_medium with a value of social, without it being used for tracking, so that gets removed.
But if someone builds a website that puts your full name into a parameter called potato, there's just no way to automatically detect and remove that.
Yuuuup, found out the hard way that tiktok shows you when someone watches a link you sent them.
My dad loves sending me cat videos on the tiktok, he sends me the links on Facebook.
I have two tiktok accounts because I knew there was a risk that my dad would be able to find me on tiktok through contacts. My dad is a transphobe, so in order to not poke the bear I maintain a cis persona when dealing with him.
But it took him 0.3 seconds to realise that he sent his daughter a link, and then an openly transmasc account user with a similar name opened that link, and then his daughter replied to his message reacting to the link...my ears are still bringing from the phone call he made to me.
So thats how my misunderstanding of tiktok trackers outted me to my transphobic father.
(fortunately I'm a fully grown adult and can cut him out of my life if he doesn't calm down)
I've been out as queer since I was 14. I'm in my 30, he still hasn't come around.
Given his age and health, if he's planning too come around he'd better get on it quick, at this rate he's dying a bigot.
I'm not waiting any more, I put my whole life on hold waiting for him to come around so I could live my life safely. If I need to cut him out of my life I will.
I appreciate they kind words, but please keep in mind mind that it's not always smart or safe to tell a trans person to be patient. The individual will know their level of safety, and advice to be patient and understanding can in some cases case be very, very harmful.
Wait, you conduct yourself in a manner consistent with a reputation you'd like to maintain? Even when you don't think anyone will find out who you are?
What kind of responsible shit is that? Don't you know you're on the Internet?
Even when you donât think anyone will find out who you are?
I guess I do think there's a non-zero chance that somebody might find out. With advances in LLMs perhaps it will be possible to create a model that can recognise your internet posts by your writing style and/or certain facts or anecdotes you've mentioned more than once.
The fingerprinting goes waaaaay beyond Instagram. Maybe not frequently username specific, but it's still kinda weird to always be throwing out your device type, browser, and prior we page among other things
another PSA if you have an Xbox account (even for PC) and have added anyone to friends they get to see your full name, state city. It is very cool to play games while also doxing yourself. thanks Microsoft
You can go into settings and change it so that it doesn't show to anyone. But at some point they made an update and it reset those options to the default setting even if you had previously set it to hidden.
At that point I just went in and changed my name on my account settings.
Ever since I realized TikTok creates a unique share URL that tells the person youâre the one sharing it, I became paranoid with any social media share links that are created dynamically. I wonât share them unless I try them out first.
Its more effort but I do this if I think its worth sharing a link, test the link in a private browser first. I just also don't want to be doxxing friends and family to the platform in question either.
Let's just share content and not track people and accounts
It's the reason I don't use share buttons. The YouTube link is clean (afaik, idk if they encode data into the ID) when copying the URL. Same with other services.
