I know Lemmy is about to take off because the porn is quickly moving from drawn henti and furry images to gonewild onlyfan contributors. I call it the QOTP Index (Quality Of The Porn). Reddit is done.
People who post or interact with porn also post other stuff.
Tumblr died after they killed off porn, because porn users left the site. That made Tumblr less interesting for people who followed those porn users' non-porn content, which meant that some of them left. Which in turn made it worse for people following that second group, and so on.
The same might happen the other way around. One can only hope.
Tumblr didn't die. It's still around. It's biggest issue is it's shitty search function, not lack of porn (which they did need to remove due to all the cp on there)
To be fair pornhub had to nuke the majority of their user submitted content because they couldn't evidence that it wasn't illegal. I can understand a company that doesn't actually want to be a porn site just blanket banning.
Reddit is the only site I've seen that had a problem with it actually handle it, Twitter absolutely didn't, insta didn't, Tumblr didn't, 4chan kind of did but became a klan rally in exchange so I'm not really sure you can call that success
Er.. Tumblr spent many years trying to combat all the cp on their site. They were losing, so banning porn entirely just made the most sense. Did it suck? Yea. But it wasn't the end of Tumblr.
