Way to lose your site user: ban them

I haven't used StumbleUpon for a long time and when I wanted to use it, this is what I get.



OK, so some spammers used my dynamically allocated IP address and created a lot of accounts and StumbleUpon banned the IP to protect themselves.

But I'm a logged in legitimate user and I'm also banned? Well, I won't bother contacting them for this. I'll simply don't use it until I feel like it, which might be a few months, a year, or never.
