EBay's community forum is buzzing with angry sellers calling for a week-long strike from 18 February ahead of the proposed change which is due to take effect on 20 February.
"I read about the strike on the other boards, so I think the message is spreading," said 'mrskillion' on the eBay community forum.
"We have just been left powerless. We need to take back a little bit. If we all band together eBay will notice. I believe that completely."
Fellow forum member 'mole314' wrote: "I've never posted here before, but I'm here now because of this fiasco. I have some stuff to dump before closing my account, but I won't be selling anything that week."
EBay spokesman Usher Lieberman admitted that the company had anticipated a volatile response to the proposed changes.
"EBay has always had a very passionate community and our members do not hesitate to tell us how they feel," said Lieberman in an email.
"Over the past week we have presented them with a tremendous amount of bold changes and initiatives, and they have a lot to absorb.
"If our community was not reacting loudly to what we've announced, that would have been a real surprise and something to be concerned about."
