At least twice I found AbuseFilters that prevented people from testing extensions that I develop or posting feedback about them on MediaWiki.org and the beta testing sites (such as http://en.wikipedia.beta.wmflabs.org/wiki/Main_Page ).

One of them filtered out the whole Russian alphabet, so the extension couldn't be tested by Russian-speaking users. Another one didn't allow submitting Flow posts that don't have a sufficient amount of English words from users who have less than 6 edits, so users who have a lot of edits in their home wikis, but no edits in mediawiki.org, and who want to post in languages other than English are blocked. Luckily, one of those people pinged me directly, but I don't know how much useful feedback was filtered out and lost.
I have also had issues with AbuseFilter filter false positives on mediawiki.org. My approach has been to disable the problematic filters immediately and leave an explanatory note at https://www.mediawiki.org/wiki/Project_talk:AbuseFilter.
