A eBay rep killed my project by flagging the account for fraud after I asked to speak to supervisor (she refused three times and the account was magically flagged the next day). All of my listings got suspended. It made the whole project untenable costing the client thousands. There was no fraud, there were no signals of fraud , just petty spite. I’ll never use eBay for anything important. Nobody should ever use eBay for anything that matters.
