As cheating, selling credits and being a multi are the reasons wgt seem to ban It probably is right that this account has been suspended as wgt think you have more than one.
That is assuming that wgt would suspend a L112 Master who has played 13,087 rounds over 8 years has no earnings ($4.50 from tiering up) and scores about 40 on the B9 at KI although he plays it continually. Someone with a 4-20 MP record. In short doing no harm at all to anyone. While at the same time hacks who have been here for a couple of weeks can shoot 57 in tournaments and still be playing.
Really, suspended as a multi?! Surely the rule on multiple accounts is to stop players gaining an advantage by being at an artificially low tier and therefor winning....whatever they are playing. He's just not doing anything hurtfull to anyone else.
Mariho if the issue is you want to score 31's again, as you must have done at some point, join a cc and set up a tournament on KI B9 from red/hack tees, you'll even get putter pal free. Or start your own CC and do the same.
I'm not sure what account you'll be able to it from, it seems crazy to me that it can't be this one, but you better just play on one.
