EBay is facing a backlash from its users in the form of a global boycott on May 1.

Founded in 1995, eBay last year generated £3.8 billion in revenue. However, president and chief executive John Donahoe, who joined the company in March this year, has implemented a number of changes that have made users so disgruntled they have resorted to boycotting the service for one day.

Previously, sellers were able to leave comments about buyers. Under Donahoe's new rules, however, sellers can only leave positive but not negative or neutral feedback. Although some users are concerned that these changes will make it difficult to alert other users to fraudulent or malicious buyers, eBay claims it will make it easier for sellers to report 'bad' buyers and will remove unfair feedback.

And while users have seen listing fees reduced, the fee eBay charges on completion of a sale has risen to 7.25 percent of the total sale price, from 5.25 percent.

"We are a marketplace founded on trust. If people have a bad experience on our site, caused by a poor seller, then they will no longer use the site. The changes we announced recently are unashamedly focused on protecting buyers," an eBay spokesman said .
