If you receive an invite for the the Social Networking site–whether it’s from a friend you trust or not–please read what others are saying about this service before signing up yourself. You may wind up spamming all of your contacts with an invite.
There are many threads on the Internet about this. Here’s one.
“While you were Burning / vacationing / spacing out offline this Labor Day weekend, many folks online were hit with invitations from a social networking service called Quechup that violates your address book, and abuses user trust by spamming all your contacts.”
Interestingly, it appears that Quechup is not the only social networking site doing this.
My advice: Be very careful sharing your contact list with any service. I realize Facebook and the like have been polite about this so far, but it doesn’t take much to imagine how this could get out of control.
I know that IE has some phishing features that warn you about giving away personal information that you probably shouldn’t, but it doesn’t seem to have any warning messages for Quechup. Should it? I think so. You be the judge.
