PayPal will lock your account and ban you for ever if you recive too many gifts and familly and friends payments from many different persons. This also happened to me and i got several perma limited accounts. PayPal get directions from thier superiors to limit and restrict accounts that doesn't pay FEES. What this mean? If you recive money and a part of that money is hold to PayPal, they will not "ban" your account, but if you keep reciving payments as gifts or familly and friends (which does not require senders to pay FEES or recivers, they will lock, limit, ban or whatever else.
I writted all in a rush because i know the exact reason, hope you understand.
