- If it's all software as you say, then OP creating his own listing won't stop others from continuing to list on eBay.
Your prices will be cheaper than the dropshippers. When people search for your items relevant items come up first. If you're selling more than the dropshippers your items will come up before theirs. Also went on the page of the dropshipper eBay shows relevant items. Your exact picture will show up with a cheaper price.
- Why should OP have to compete against other sellers using his IP? Lazy dropshippers stealing content can and should have listings remove which consist entirely of stolen text and photos.
Lazy dropshippers providing more sales for you on markets you're not in yet. Yeah, sounds horrible.
- eBay will ban a seller for continued IP violations.
Sure.
