Same with me. If I lost my Twitter account, I could rebuild it -- my _actual_ following at the time had more to do with my blog and RSS (miss those days :( ); however, it shows that you can't really trust that an account is yours or that as long as you follow rules, you get to keep using the site. Or that you'll get a "fair trial" when you're accused of breaking rules.
It doesn't help that these companies also punish you for getting accused when they _do_ have manual review. One of my photos on FB got mistakenly flagged, reviewed and approved that it's fine, and I still had a 7-day ban from posting/commenting. Youtube has that 3 strikes rule or whatever where if you get accused 3 times or more of copyright infringement (even if false and retracted), you lose monetization.
