Due to suspicious activity, account locked.

"Due to suspicious activity, this account is locked.
A message has been sent to this account's email address containing details on how to resolve this issue."

Every time I log in when I use WoWTunnels, my account gets locked.
Every time when I log out and log back in, my account gets locked.
Every time I disconnect and log in, my account gets locked - very frustrating during raiding.
Every time I change tunnels, my account gets locked.

Can I get on a white list to prevent this? it's driving me nuts, I chose to use the tunneling service as I live in Australia (500ms vs 190ms).

I also use an Authenticator, and have done so for a long time.

I can tell you all the IP's which I have logged in from - as well as all the WoWtunnel's IP's.

Any form of help would be appreciated, this has been an ongoing issue - and it happens to ALL our guild members.

Thanks in advance!
