Everybody knows Bob Geldof doesn't like Mondays. He apparently can't tolerate scalpers--or their enablers--either.

The ex-Boomtown Rat turned charity rock icon, lashed out at eBay for allowing Netizens to auction off tickets to his Live 8 mega-concerts. Because the shows are aimed to raise awareness to the problems of developing countries, Geldof said those who managed to score free tickets via lottery should not be "profiteering on the backs of the impoverished." The Irish rocker called eBay an "electronic pimp" for allowing the tickets to be put on the block for exorbitant amounts--more than 100 pairs were offered for sale, with some fetching bids as high as $1,800.

"I am sick with this," Geldof said in a statement. "The people who are selling it are miserable wretches but far worse is the corporate culture which capitalizes on people's misery."

He urged a boycott of the online auction house and then called on people to flood the site with either phony Live 8 ticket offers or inflated bids.

"What I would ask you to do tonight is to get on eBay and mess up the system," he explained to Sky News. "Everyone should go on and pretend they have got tickets for Live 8...Otherwise, go on and bid ridiculous amounts of money for the tickets already on the site."

And that they did. Live 8 tickets originally going for a few hundred dollars suddenly surged to a few million, prompting eBay--which initially balked at Geldof's demands--to suspend the auctions, and halt the enfolding public relations nightmare.

"We've listened carefully to our customers," Doug McCallum, the company's managing director, told Britain's ITV television. "Overwhelmingly the voice is that they would like us to take down the listing."

However McCallum did point out that reselling tickets for charity concerts was not against the law in the U.K.

For the most part, Geldof was pleased with eBay's decision.

"Well done for taking them down," the musician told Sky News after eBay's move. "But it was despicable, and they should have thought about it before they did this."

The Live 8 concerts, five of which are slated to be held on July 2 in Rome, Paris, Berlin, London and Philadelphia and a sixth show in Edinburgh on July 6, are intended to pressure leaders of the G8, the world's most powerful industrial nations, to do more to help the Third World.

More than 150,000 free tickets for the Live 8 show in London's Hyde Park have already been distributed via a text message lottery system (the 2 million text messages sent in made the lottery the largest of its kind in history according to the Guinness Book of Records). The London show is the marquee event, featuring performances from the likes of Paul McCartney, U2, Coldplay, Madonna and a reunited Pink Floyd.

Among the other big-name performers scheduled to take part in Live 8 concerts on July 2: Dave Matthews Band, Bon Jovi, Stevie Wonder, Will Smith, Sarah McLachlan, Jay-Z and P. Diddy in Philadelphia; Jamiroquai, Placebo and Andrea Bocelli in Paris; Lauryn Hill, Brian Wilson and Crosby, Stills and Nash in Berlin; and Duran Duran, Faith Hill and Tim McGraw in Rome.

Annie Lennox, Dido and Travis are among the artists headlining the Edinburgh show on July 6, which is the same day the G8 meeting kicks off in nearby Gleneagles. Geldof has called on 1 million people to march to Edinburgh for the cause.

But eBay isn't the only headache for Geldof this week.

His former mates in the Boomtown Rats have threatened to sue him over unpaid royalties they say they are owed from 14 U.K. singles from the 1970s and 1980s, including the band's signature hit, "I Don't Like Mondays." The Rats, who released five albums and had two number one singles, broke up in 1986 not long after Live Aid.

While Geldof is credited with doing most of the songwriting, Gerry Cott, Simon Crowe, Garrick Roberts and John "Johnnie Fingers" Moylett released a joint statement saying they are pressing ahead with claims for "their rightful entitlement to a proper share of recording, publishing and merchandising income." They've also requested financial information from Universal Music, which controls the Boomtown Rats' catalog.
