Quechup Mess

If you get an invite from me to join a social network called Quechup, please ignore the e-mail and accept my apologies. It's some kind of viral campaign, in the worst virus-like sense.
Let me explain. I received an invite this morning from someone that I know well to join eh... yet another social networking site. Well... I decided to quickly check it out. One of the features is to compare with your address book who is already a Quechup member. Then, apparently, Quechup sends out invitations to join to my complete Gmail address book :( - without requesting any permission. This is crap. This is very very annoying. From what I could see, many people got caught and want revenge.
So, spread the word and check if all the story is as bad as it seems to be.
