Its not a ban wave, ban waves everyone gets banned, and thats everyone.
This is the first bunch of bans in a while but that does not make it a ban wave.
If it was a wave, you, me, that guy and my dog all get banned.
Its helpful to know what caused it as it is not detection. So a properly filled out ban form tells us, Is it gathering, dungeons, battlegrounds, etc that is causing bans.
Blizzard if not nailing everyone in a wave will sometimes take action on the obvious shit, like herb farmers. Markets on many servers have crashed due to so much supply of herbs and ores that people are crying. I for one know that i cannot farm the gold to make my months time in the time I was.
Its like when battlegrounds were being hammered because people are crying. Blizzard reacts to please there other customers. And they do not kill every botter every time because botters still bring in revenue. they do enough to keep people in check.
