I would definitely complain to eBay — this needs to be stopped ASAP. Anyone, and everyone, needs to point this stuff out to them for every single transaction where the same message is essentially being sent by “multiple” sellers. The more this happens, the more likely eBay will attempt to do something. Who knows if it will be a positive outcome, but it doesn’t hurt to do the due diligence required. In the past, bad sellers were shut down, so I don’t see why this wouldn’t happen today — unless China owns eBay now.
