I think 1 robot is enough for people who are really interested in chatting to notice it, but yesterday I saw like 7 or 8 Wolfy's chat advertise bots at same time just sitting in the lobby instead of playing, so much inactive robots make players leave the lobby after all the challenges are ignored, it's what I call agressive advertise... I need 2nd bot to be able seeing what robots that challenge me got and I remove it during battles, advertising at same time is just a great benefit, but what you are doing is wrong.
