Rolling Back due to one theft from one place is one thing, rolling back due to a bunch of n00bs, downloading anything willy nillie is another. Fact is this, in this instance, a roll back would be poor... another fact.. its not going to do anything impressive till those coins are sold.

The infected link was in a quote of the dev, the attacker changed the link.... because developers from bitcointalk don't have any skills to protect the hyperlink function, like they are not able to make a avatar function for us.
Problem is Bitcointalk.com and his unsecure hyperlink function, firstly.
Secondly, nothing (oh wait... you are the biggest dumbass that don't verify anything, talking random shit, ect)
