Trade isn't an opinion.
You either scam someone, or you don't.
If you check
my sent feedback, you'll see I've tagged several Scammers without being scammed. If something is an obvious scam, I prefer not to get scammed first, and tag them as a warning to other users without trading with them first.
Or are we just arguing whether knowingly promoting a proven scam is untrustworthy behavior?
This is a more more interesting discussion. I'd say it says a lot about someone if they're willing to promote a known scam.
