Well, maybe three days isn't the worst part of it, but you also get some sort of criminal record :? Anyway, give CS until monday. You'll probably receive a reply, and if you asked, they should tell you what kind of offence you actually commited, too. Also, as for not replying to players, sure, some will report you for macroing or whatever, and you'll (eventually) be checked by the system, but if you're innocent you shouldn't get an unfair ban or anything. I've never gotten into trouble because of it myself, so yeah.
