That's a shame, I bet Valve haven't refund you your 100$ right ?
In that case, you may go around and release a "nicer" version of your game which won't be banned, whatever the reason, call it something like "-lite" "-whatever", and add a note somewhere to explain why and what and how to get the censor-free version.
So you won't loose 100$ to weak morons who prefer to keep them relatively safe for now than actually taking a stand for their users AND main income source.
Such a "retreat" from Valve may lead to the loss of Steam in the future if they don't do nothing about it, as who will bet on them if there is even a 50/50 chance to get ban ?
