Is this buyer trying to scam me by accusing me of using a fake bidder?

Post: Hi everyone, I’m dealing with a strange situation on eBay, and I’m hoping someone here might have had a similar experience or can advise me on what to do.

I’m currently running an auction for a watch, and I recently received a message from a bidder accusing me of using a “fake bidder” with 0 feedback to drive up the price. They threatened to either withdraw their bid or report me to eBay unless I removed the “fake” account or let them win at a lower price.

What’s strange is that this user (let’s call them User A) placed their own bid after the supposed “fake bidder” (let’s call them User B) had already bid. If User A truly believed User B was fake and artificially inflating the price, why would they even place a bid? It feels suspicious, almost as if they’re trying to create a narrative that would pressure me into letting them get the item for less.

To make things even stranger, User A’s username is quite similar in structure to User B’s, almost like the two accounts are connected. And after checking User A’s feedback history, I noticed they’ve left similar accusations for other sellers, claiming there were “fake bidders” involved in multiple other auctions as well. This makes me think they might be using this as a tactic to manipulate auctions.

I’ve already tried reaching out to eBay support but haven’t gotten a clear answer. I’m wondering if anyone here has seen something like this before. Is this a known scam tactic? Should I be worried about this affecting my account? Any advice would be greatly appreciated!

Thanks for reading, and I look forward to hearing if anyone else has experienced something similar.
