I've just started to see this notification since moving to Canada from New Zealand. Could this be due to the change in IP address?
"Your IP Address (***.***.*.***) has been suspended for 11 years 10 months due to Suspicious Activity"
I'm still able to login and play without any issue and I have read that logging in with a clean IP address will resolve the issue eventually. However, I haven't been able to make the message go away.
I guess it's not a huge deal, but I have wanted to donate and do a couple of other things in the store/shop which I now no longer have access to.
