And by banned from fishing im referring to where you set your bot in one spot and fish, not poolfishing
As with most of the bots, the bot is not detected the behavior is.. Mostly by players reporting. If you stand in the spot just fishing for 10+ hours people are gonna report you, And if you get reported blizzard is gonna look at your logs and if they you have been fishing at that spot for 24 hours, they will most certainly ban you. If you dont wanna get baned do everything in moderation, and try to make it as human as possible.
