fix: Unnecessary restrictions on bad word filters

Browse Source 
Bad words can now contain almost any character and match domains, accounts or hashtags more precisely. For example: `example.com` is no longer split into `example` and `com` which would block more than intended. `#example` is no longer redurced to `example` which would also block the word, not only the hashtag.
