There seems to be a recent increase in the number of trolls "playing" on BBO and it is extremely frustrating. Those trolls that concede all tricks or bid 7NT just to foul the board need to be eliminated. I don't know if most of the trolls are 10 year olds or just idiots thinking they are funny but it ruins the game for all of us. BBO needs to do a better job eliminating thesis people and perhaps it should start with requiring all people to post at least a first name, a cow try and a rudimentary profile. Most trolls I have run into have none of the things.
