https://en.wikipedia.org/w/index.php?title=Special:AbuseLog&wpSearchUser=88.230.103.208 keeps getting multiple entries per edit (2023-10-05T14:55:08), this time through https://en.wikipedia.org/wiki/Special:AbuseFilter/1199 alone.

I set up public filter https://en.wikipedia.org/wiki/Special:AbuseFilter/1269 to test this. It currently trips on any three edits, by the same user, to the same page, within one second. It already has almost 100 hits in less than a day. I have no idea what the other users are doing, but I was able to trip it by attempting repeated identical edits:

for(let i = 0; i < 5; i  ) (new mw.Api()).postWithToken("csrf", {assert: "user", action : "edit", title: "User:Suffusion of Yellow/sandbox", text: "y"})

Note that there's only one actual edit being committed here; there others are all null edits which should not be tripping the filter.

Of course, this is a contrived example; the real cause may be unrelated.

It looks like almost nothing has been said about private filters so far, beyond a few throttle settings. I think this task can be made public.

others are all null edits which should not be tripping the filter.

This sounds a bit like T198651: Abuse filter log is showing wrong information. AbuseFilter does sometimes detect null edits when they reach its methods.

It's still happening, as pointed out by @Mathglot:

Database error
To avoid creating high replication lag, this transaction was aborted because the write duration (5.3958411216736) exceeded the 3 second limit. If you are changing many items at once, try doing multiple smaller operations instead.
