Please be aware betfair are experiencing major problems where accounts being empty rang betfair and they are trying to resolve issue may cause problems for uk members who run bots over night
I think I remember a time where you could geo-restrict bets on your account? But can't see that now for some reason. Two step authentication is a must though.
I've just looked on the self-exclusion part of my account. The restrictions i have ended in 2012 by the looks of it, and the only one I can renew or update is a self-exclusion from Virtual sports
