Is stumbleupon.com Safe?

When I went there it said I needed activex, which I didn't enable, thank you mozilla! A few seconds later, Norton said I was hit with Generic.200 which is a trojan horse. But it is wierd because no one else has had a similar problem, maybe my browser was exploited and redirected to a faulty site? I got the link from Digg.com too! Somethings fishy...

PRIVACY BREACH ALERT!!!! I've been a member of StumbleUpon for over 2 years. This incident still has me shocked. I recently tested the new "toolbarless" web based StumbleUpon user interface to send a "stumble" (share a web page) with my subscribed SU friends. This user interface without my consent or prior warning disclosed my private e-mail address to these other members. Was only alerted to this unwanted privacy breach by on screen message AFTER I had clicked send. Any veteran member of this community would have anticipated this to go to the SU members Stumbleupon PM inbox or "stumble" queue. That is how stumbling pages is normally done. Not using my private e-mail address or my SU friends e-mail addresses as this new feature did. Still have yet to receive official explanation from SU site admin/owners and I'm not holding my breath waiting. CAVEAT: If you use this site, make darned sure you register using an e-mail account you can treat as disposable or don't mind being shared with strangers. Lucky for me, that is what I do for all sites. Sadly many do not and there is great risk to personal privacy. Beware!
