eBay is refusing to allows users to sell their winning lottery tickets to attend Michael Jackson's memorial service in Los Angeles today.
The online auction site said it would remove any listings of the tickets because such sales are "inappropriate", according to the BBC.
Tickets were issued on Sunday to 8,750 ticket winners out of the over 1.5m people from around the world entered the lottery draw.
Within hours of the tickets being issued, winners began offering the tickets to the highest bidder on eBay and advertising site Craiglist.
The move was greeted by a storm of protest by fans.
They pushed up bids on eBay to tens of millions of pounds in an attempt to prevent ticket holders from profiting and flagged ad as "inappropriate" on Craiglist.
Jackson's memorial service is expected to be the biggest event in web history, with several TV stations planning to stream the event live over the internet.
The event will be a major test of the streaming technology as many news sites
struggled to meet demand in the hours following Jackson's death.
The average response time from news sites was almost nine seconds, which is more than double the normal response time of less the four seconds.
