People never stopped. It dies down a little when Valve does a VAC wave but then kicks right back up when the game goes on sale and people snatch up a bunch of accounts for cheap that they don't mind get banned. ESEA has a subscription ($6 monthly) which is actually pretty nice. It deters cheaters (some still exist) as cheaters generally won't cheat on an account they are paying a subscription for. ESEA supposedly also has a better anti-cheat than VAC. Only problem with ESEA is everyone is a try hard because they are paying and don't want to deal with a MM style environment.
