At lunchtime on Tuesday, numerous pairs of tickets to the Live 8 concert in Hyde Park had already appeared on . Geldof has responded by calling for a worldwide boycott of eBay and said he was considering taking legal action.
However, eBay users appear to have taken matters in to their own hands, with a large number of the tickets on sale receiving astronomical bids, including one pair that are selling at £10m.
Geldof has contacted eBay to ask it to halt sales, according to reports, but was turned down. According to a report in the Evening Standard, Geldof has been told that he should wait until there are 1,000 ticket offers before launching legal action in the High Court to make eBay take them down.
"Nobody should buy these tickets. It doesn't matter if people sell them for 1p or £1,000. If someone doesn't want them they should give them away," Geldof said.
EBay has offered to make a donation to Live 8 and said it did not want to profit from the auctions.
The texting campaign to win free tickets to the gig was hailed as one of the most successful to date by O2, which ran the technical side.
Live 8 is to be held on July 2, ahead of the G8 summit in Edinburgh. Artists performing at the London event include Madonna, U2 and Pink Floyd, while Stevie Wonder and Bon Jovi will perform at the Philadelphia concert.
