Pleroma fetching old posts of newly discovered users
Since recently, pleroma started fetching a lot of posts of newly discovered users. It's almost always very old posts. Sometimes there's several tens of them.
It started recently after an update. According to reflog, 745375bd is the one that has it and a9bc652a is probably the one that does not.
My theory is that it's something with the pinned post fetching: !3312 (merged)
It lies in the aforementioned commit range and pinned posts are usually old. It would seem that it may be fetching entire pages instead of single pinned posts.
The problem is that it happens for all newly discovered users and their year old posts come flooding the twkn, which is very annoying and makes it practically unusable.
