I can relate to what you're saying. A similar thing happened to me on GameFAQs. Someone had posted a little 'challenge by-pass' for Jak 3, and I was gob-smacked that I didn't think of that. So much so, that I ignored the rules and censor bypassed the S-word using #, ! and $ (not in that order) many, many times in a single post. Of course, I didn't know that there was such a thing as censor by-passing, and so I was promptly banned one Friday afternoon. The neat thing was that I was helpful and friendly enough beforehand that several other users got upset, and I was able to contact one of them via PM on Gamespot (Gamespot and GameFAQs are affilated), and he told the others what had happened. The battle to get me back on continues to this day...
Back on topic, I reckon you should stay, because you're new and have good intentions. If you've checked my profile, you'll find I have Asperger's as well, but what you probably won't find out is that I'm just 16 (but I feel like I'm 14). If you can't express your anger at them without violationg the Terms of Use, then do it in Smileys! Just make sure you're not spamming...
And yes, there are mature people around here. In fact, I'm both! I can type what I just said and yet I always chuckle when someone farts in an exam...!

But then I found
That I could speak to her,
In a way
And sadness turned to comfort
We all go there
