Bluesky - the Social Network where everybody posts screenshots of the awful things people post on other social networks!
I registered bluesky account for the second time last Friday and I've pick no interests during first login. Last year I had Discovery feed filled with drawn porn despite of my settings. And now on a fresh account it's mainly American politics - while setting are more liberal regarding adult content. I followed nearly 60 people but only few of them are active. The global stream overall seems to be much "slower" than public federated one on mastodon. My partner complains he gets furry porn in Discovery while having a zero interest in that - he follows only 11 accounts.
I haven't bumped on screenshots from twitter so far.
AFAIK the 'Discover' algorithm is based largely on _likes_, not who you follow. This can result in extremely weird results for people who never like posts, which I suspect is quite a large part of the user base.
(I wish the number of users who blocked an account would show up next to the number of followers)
