Right now, as I type, there are at least 30, and maybe as many as 75 bots farming the moonless walk in coldharbour.
It just seems that they know it is very unlikely they will face bans, and they are really ramping up the farming. The don't try to hide or be subtle about it. There are at least 3 trains of 10-15 bots where I am, and I hear zone chat talking about other bot trains in the city and other parts of the zone. This is not even getting into bots camping boss spawns, etc.
We all tolerate not having an auction house or whatever, because we were told it would minimize gold farming and gold seller spam. In my experience however, this game has as many bots and spam as any mmo I've ever played.
Please try to increase your efforts to remove the bots and gold sellers.
