Same. The guy didn’t change any of my profile or recovery info, luckily, so I was able to get it back. And then he sent me a message from another account asking why I had taken his UIN. We ended up chatting for a while. It’s a fond memory.

I actually tried to delete that UIN a few years ago, but the support folks wanted me to provide a few UINs from my contact list to verify ownership. No chance I’m going to remember those.
