(Please move this if it's not in the right area. GD seems appropriate enough to me at least.)

So I've been getting weird messages at login with increasing frequency recently. The first few I was happy to ignore and follow the link to reset my password, but it's happening often enough nowadays for me to start wondering if anyone else gets 'em as frequently as I do. (If enough do, I'll assume it's some sort of problem and not the more worrying option, that someone, for some reason, is trying to access my account.) Here's the message.

"Due to a change in your connection settings or the detection of suspicious access to your account, login to your account has been temporarily restricted."

First, there's been no connection settings change. Second, I have one service account so someone else around where I live hasn't attempted to log into theirs and got it wrong. Furthermore, I've never gave out my password or login details to anyone, or gave any friends the means to use my character for whatever it is they do. Third, this computer's clean. So seriously, it's neither of those things.

It's happening really frequently lately. Has anyone else noticed anything like this?
