As blogged here yesterday:  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. Now that people are coming back from the Labor Day holiday, expect a bunch of invites -- I've received a dozen just this morning. Delete 'em if you know what's good for you. Link to one of many first person accounts, Link to another. And another, and another (punch line: the spam blast created by Quechup caused Google to suspended that victim's Gmail account). Update: via Howard Rheingold on Twitter, here's the corporate rep info for Quechup:
