I ran a small test and apparently the word f****ed isn't.
>"Of course it isn't censored"
>none of the swears in past tense are or plural for that matter. it's just a thing
Better Answer: Yes, as per your "small test", that word is not censored. . . . It most likely never will be censored either, because variants of censored words are of too many kinds. Censoring every one of them is not feasible. That's why we have mods and editors to kick out anyone using them.
