On itwiki I set a filter which allows 1 action every 90 seconds, grouping by "user", and then prevents the action. However, today I found this entry where the action was disallowed even if that IP didn't make any other edit in the last 2 days. The AbuseLog is also empty, so basically this was the first edit and it got disallowed, while it shouldn't. I came to test this on beta cluster, where I created a similar filter (allow 1 action every 30 sec, group by "user", then disallow) and it correctly let me make the first edit and disallowed the second. I'm not sure why this happened, but right now I can't investigate so I'm putting this here as it is.

OK, either I don't understand it, or it's completely broken. For the same filter, there is this hit, which blocked the user. However, the filter is set to only block the user after throttling, and throttling is set to allow 2 actions every xxx seconds (private filter, don't want to give away too much info). This is surely wrong, since it allowed 0 actions, and blocked at the first edit.
