After doing a little testing I found that banning does not occur unless the second notification window appears to the person logging in.
It would be nice to have this banning action occur on the first message of notifying the register of using a proxy server.
To test this I used this and was caught

and this one got through do to it not getting the second notice

I still like the hack but just wanted to pass this along as I am really getting hit hard by an idiot.
