There's a YouTube video from a guy named Michael Reeves, he set up system of FB bots that will message someone on marketplace about a product, but very rudely. Diminish the product, argue the value, etc. and make a crazy low-ball offer. Then a few days later after the seller has dealt with rude low balling bots he messages them as himself with a polite, and low but reasonable offer that the sellers take because they're happy to wash their hands of the matter. (Disclaimer, at the end of the video there's a compilation of him revealing the scheme and paying the sellers the full list price of their item). The unexpected part is there were sellers who accepted the shitty offers from the bot, and he didn't have to follow up. All this to say, some people act entitled because it's been rewarded in the past.
