I had a similar thing happen to my Yahoo account in ~1998-1999. After I'd been using it for a couple months they decided to ask everyone "Are you over 13?" and being a foolish honest child I selected "No". Permanently locked out. Tried to get back in after I turned 13, no luck. Well crap. That's literally how I ended up `donatj` instead of `jdonat` basically everywhere - got permanently locked out of jdonat@yahoo.com I have a fair number of active accounts to this day that I've had since before I was 13 cough ebay cough in the late 90s. I'm scared one day they're going to cross reference the creation date with my current age and be jerks about it.
