its hard to know whether this exuse can be accepted.
One one hand it may be the truth, and in some cases having a member of your family cheat and you also getting banned is a plain bitich, i know it wouldn't be very nice if one of my housemates cheated and i too got banned.
but on the other hand, how can we be absolutely certain thatthey are tellign the truth. I guess this is another case where a login system jits has been discussing could help alot.
