That is odd. I'll have to download Tor and experiment
Wont have a lot of time for a couple days (weekend) but will see what I can find.
I know we use an IP Check in the security stuff for banned spammers, so maybe an encrypted IP is seting it off. A quick look at the settings showed no easy answer to this.
I called it odd because I have been using a VPN for years and never encountered this issue. My VPN either sucks or is really good!
