Well, today we've found out that the creater of the MySpace Samy worm has been sued by MySpace and sentanced: http://www.scmagazine.com.au/news/45262,myspace-superworm-creator-sentenced-to-probation-community-service.aspx
I'm honestly lost for words, that comes as quite a shock to me.
Now clearly he has done something wrong (and now it seems - illegal), but I don't think anyone expected this. Especially considering that while it did spread, it was completely non-malicious.
For the moment I'm safe since I've never attacked MySpace, but frankly, I'm just worried that they're going to come after people who have disclosed vulnerabilities in MySpace next.
