I've been having this problem a lot recently. First Rackspace, later CloudFlare. Most recently Twitter accused me of being a robot and asked me to verify that I'm a human by posting a government-issued ID even though I rarely use it and I've never posted a comment there and could not have possibly broken any policies. Sorry that this is happening to you. I think tech companies at large are really failing individuals. Even if it's only 1 - 2% of users annually, it adds up across the dozens of services we use day-in, day-out for years and it really isn't good.
