Cheater is a real problem on CSGO ?

Well... In 3 months I've played about 100 matches on CS:GO competitive, with prime, long term account (more than 10 years of cs, high rep and stuff). In those, 60+ games had people vac banned for cheating.

Even guys that were lower in scoreboard than I. This is just horrible, because even if you do pay the game, people usually buy prime accounts to cheat.
