I watched this last night. On the whole it was a pretty stupid programme with equally stupid people not knowing how to report and block people. Why not just ignore sites like littlegossip, and why have a formspring account.
"I love that the whole thing is narrated like they're tracking down an animal in nature. I loved the end "So, there you go, an internet troll. That's what they look like." Yep, that's what they look like." - this did make me giggle though.
