Update to our earlier announcement of kbin.social being temporarily blocked:
Unfortunately, the porn posts have continued to appear in our new feed for over 12 hours now. It's clear that we can't user-ban our way out of this.
Blocking kbin.social was a temporary measure that allowed us to stop the flow of spam posts, wait a while to see if kbin.social had gotten the problem under control, and then re-open the gates to check to see if more bots were posting links. Every time we checked, they were. However, they were studiously keeping to the [email protected] community, never once posting in any other community.
For now we have decided to remove the community and leave access to the rest of kbin.social open. This is a little risky, but leaves us connected to the rest of Kbin.social's content. If you were a subscriber to that community, you won't see any past or future posts in it. Nobody will be able to search for that community from lemmy.ninja, either.
We'll keep an eye on the "New" feed and take action if the bots migrate to another community on kbin.social. For now, however, consider them in chains!
Glad this was taken care of. I browse all a lot, and lemmy doesn't really have any controls in place to block NSFW yet. Granted, I don't mind NSFW in my ALL feed, but it was so egregious that I was seeing 8-10 porn posts in a row over regular posts where normally that ratio is flipped.
