This seams really stupid since account sharing is against pokerstars rules and will probably end up in getting the accounts banned if you do lots of transfers between the accounts you share. Seams to me like building a card house when you share so many accounts and transfer so much, cuz you stake a bunch of players right?
I would just be scared that suddenly pokerstars dropps a hammer on your activity. They have IP longs that shows who loggs into the account, just like FTP has, FTP even has a option to look on those logs yourself.
This is why i find account sharing a stupid idea, but maybe its not, dunno. Am i wrong here?
