This seems to have about a half a hundred solutions - Changing listing voids prior reviews - Changing product category voids prior reviews - Enable transferring reviews by a paying a fee which will pay for a human reviewer to approve this - Make people put up a bond to sell goods and or agree to a huge fine if they do this. When you find people doing this take their bond and or fine money out of the money they would have received for their goods. Also delete all their listings and ban them from the platform. If any account attempts to do business in a way obviously linked same card same email etc ban them too. - Find mismatches between reviews and product by having a program classify reviews by probable product type reviewed and have a human review hits starting with the most prolific offenders and bring down the ban hammer. If you can actually collect fines directly out of money intended for the scammer this trivially pays for the enforcement activity and improves the health of the platform. If the economics of the scam are I'll make a little money to if I do this at a large enough scale to make any real money I'll probably be caught and lose money it doesn't look like an attractive scam to run anymore. It's not necessary to be perfect just good enough to mostly resolve the issue.
