Probably because it literally says you're not allowed to swear in the terms of service. The filter is there as a sort of shield, but it doesn't mean it negates the rules.

3.3 Profanity and Offensive Language. You may not use profanity or any language that a reasonable person would find offensive. The Game is for players aged 13 and older. You agree to behave accordingly.
Don't shoot the messenger, I'm just pointing that out and obviously people do swear all the time, but as I'm sure you know unless it's reported to SE they don't do anything about it.
