It seems the censoring parser bug was not completely fixed. In post content, the word censorer replaces characters of censored words by ■, and for topic titles the censorer blocks posting until you change the title.
The bug caused legitimate words to be censored if they contain censored words, that means even if the word boundaries do not match. This was fixed for post content, but not for topic titles.
that should not match since there are no word boundaries on either side.
Oh wait – you are referring to topic titles, you massively buried the lede in your first post. I’ve edited topic title to reflect and Robin can validate the fix.
