Isn't the max temporary suspension 20 days? After that, they do permanent bans. It takes a LOT more than swearing a couple of times to get that big of a suspension. I'm pretty sure there's more to the story than a few swear words.

And yes. It is on you, filter or not. You agreed to the TOS. You violated it before. You were punished before for it. You did it again. That is all you.
