If Manacube doesn't use it already, a good way to help with bad word bypassing on the Discord is through a bot such as YAGPDB that can use regex to instead of blacklisting a word, blacklist combined characters. In that case, you could for example, for the f-word, use a list of bypass characters for each letter in the word. It's also not very hard to add letters, just put it in the list. The only problem that I have found is that it ignores spaces and I don't know if you can fix that. Shouldn't be a problem most of the time.
