Most community servers have their own ways of dealing with cheaters by having their own admins to issue bans, as well as being VAC secured. I know VAC doesn't do much, but when the ID of a cheat is caught by valve, the users of that specific cheat get banned. Valve are also developing VACNET further so expect to see a slightly more competent anticheat, even if there aren't many large posts about it. And the ratio of cheaters in non-prime may be higher than before, but it'll be a better experience for those playing prime. Old players seeing the update usually come on to try new big updates, I've done that myself in the past when I didn't really play much, and I know others that come on just to play the updates and test them out.
It's also probably not worth replying to much you say because you make threads such as "SWEDEN LUL" and 'Brazil laugh thread" instead of contributing anything useful to the community.
Anyway, have fun watching CS become more popular while being both wrong and miserable.
