I think that when kibs cannot be seen by players, it will lead to some problems with stalkers. As many of you might remember, when BBO started kibs could be invisible at tables - I personally had a BIG problem with one member stalking me and making my life miserable. Not allowing players to see who is kibbing amounts to the same as being an invisible kib. I strongly feel that players have the right to know who is "up there". Apart from some ACBL tournaments, I always host - I will now either have the "Permission Needed to Kib" ON (which necessitates disrupting a game to click 'yes' or 'no' to those wanting to kib) or alternatively I will just disallow kibs completely!!
