I've just blocked 65.116.112.0/21, which is an IP range (a) owned by Overstock.com (b) widely used by them for spamming, COI editing and attempted intimidation of administrators dealing with them. I strongly suggest against unblocking this range under any circumstances; requested unblocks should probably be run past the ArbCom, who are very aware of Bagley/Overstock's odious work, before acting.
