Is anyone else seeing some posts appear in the feed All - Hot from other instances?
Seems it’s some kind of backtracking to fetch old threads from the other instances.
It looks like this (these ones are recent posts, but I saw some from 2years ago too)
That’s what was happening to me.
Seems this is normal behavior, when someone searches for a community from another instance the first 20 posts are imported to the instances you searched from. This is causing those posts to be inserted into the feed.
