4. there is 2 case: in low lever (1 or 2) it means he doesn't know the bid rule ; in higher level to indicate that he has MANY token; the 3rd case is rare but happen that's lag when your connection isn't good or you player in top11.com but signed out from facebook. 2 differents people bided but you see the same name the same emblage ... but when you clicked in they are different.

5. not really. in a quite sever you can mess for it but generally in a crowded sever we need to the last second to see if there is any token buyer bidded or number of bidder (it means also how many round you need to bid.). It's also normal that plusiers bidder bid last second and when they see a token buyer or a large number of bidder, nobody bid next round
