Risk is always the same because either Blizzard will do something about it or they won't. The exposure increases the chance, but they aren't going to go "Oh you played a fuck ton of wild pirate warrior for 9 hours a day consistently for 3 months, and then stopped right after everyone said there were bots. Clearly you are not a bot." If they are going to ban bots they do it in waves. The waves get people who have even botted once or twice. If you're that concerned, here's a novel idea.... Don't run at rank 5? Don't play pirate warrior with the bot? If everyone is focused on pirate warriors, play any other good deck.
