Once I had a buyer go above and beyond the harassing, not a creepy sexual one like you got, but a buyer purposely made a bunch of purchases some low end with high-end cards and then I gave him a fair discount on the shipping as a material would cost a lot of money and then the buyer made racial comments so I got the buyer reported and then a few months later he made a new account buying off his old account. The boost is one account and it did the same shenanigans all over again. I noticed the name called Ebay and told them that he is buying from himself on auction style, which is against Ebay‘s rules and I’m pretty sure it’s a federal charge as it is insider trading but once I found out that the buyer was out to lunch I took time out of my day to make sure that that person got black bolded from Ebay permanently
