Who here sells on ebay?

Hey, I am planning to sell on eBay and was browsing through some seller's feedback and it seems on almost all the negative feedbacks, the seller accuses the buyer to be a fake competitor buyer and the fake competitor buyer gives negative feedback on purpose?

Have such things happened to you if you are selling on eBay and any way to prevent it?

Bumping. Anyone here sells on ebay?

Been selling on eBay for 15 years! - it's very one-sided to the buyer!

I've never really had noticeable negative feedback from Competitors. However eBay customers are very fussy.

I've moved away from eBay as much as possible these days.

Sell what? Nobody bothers to leave you a negative feedbacks only unhappy buyer.
