This is probably the sentiment of just about everyone that has posted in this thread.
I have put several years into my franchise. If this crap is allowed, I let my supporter run out and quietly fade into the sunset.
I can assure you, no crap is allowed. Every time a user is reported for anything, the GM's take the reports very serious, investigate, and act accordingly. When a player is busted for an infraction, that information is not made public or discussed in league forums...sometimes other players continue to report a player or complain about that player even after he's faced consequences for an infraction.
Everything is taken serious, and everyone from the BB's, to the GMs to the everyday players know that the game is only as good as the integrity behind it. The tools that BB has to detect cheating, and aid in investigations are quite sophisticated...please rest assured every effort is made to stop those who abuse the rules, or to simply remove blatant cheaters from the game.
