False profanity hit on a non wildcard blacklist item

[dkachele]

Summary
Received a false positive for profanity on a new issue submission for the word "Supersedes", I'm guessing it was triggered by a pattern match on the blacklist item "perse" however this item does not have wildcards.

@dkachele Hi, thank you for reporting this bug! My apologies for the late reply, I totally missed this issue.

It appears that this word still gets filtered even after discarding the word "perse" from the blacklist. I will try testing it on another instance of the bot because I still cannot reproduce this problem locally.

Regardless it looks like I need a more stable dependency for filtering words. I will work on it when I have the time.
