I think it's time we had an 11pm - 3am (or another time) night shift for one of the staff.
Last week one user put up his passport number, mobile number and more important information. No staff or educators were on at this time, and one user had to phone him to get his information taken off. About 2 weeks before that; another user put up his O2 voucher code and ending in someone actually stealing that tenner
I have been checking over the forums at late times and at that time, lots of members start putting up their personal information.
Of course it's a late time, but it really reduces havoc.
