OK, I just don't want to lose my team... If I outbid this other team (either he is my brother or not) on my player, there is no reason to get banned though is there? I would rather pay then lose the team
What I would suggest doing is that for any of your players you have listed that you feel have bids on that are irregular (either because they are overbid or because you think the bidder may be someone who has shared an IP with you), go into your team's home page, choose the "Report This Team" and include the playerIDs of your players in the report and explain the situation there. It's far better to report incidents that do not look right than it is to leave them alone to be discovered without report, as when you self-report we have your commentary to take into consideration and when you do not we do not.
