I have only sold twigs, I mean CUTTINGS ;>}, on eBay one time, but have over 5000 sales over 10+ years to over 20 foreign countries for magazines related to trains and model railroads, among other items. I KNOW that if this "RottenRob" gets enough negative feedback and "report buyer" messages they will kick him off. But no one seems to want to do that enough.
One problem is that you only have a limited amount of time to leave feedback, a MUCH sorter time than it would take to grow the cutting large enough to tell that it is not what was advertised.
I contacted him and asked, "Are you going to mail out Brown Turkey cuttings, as you have to so many others in the past?" and he replied it was only hearsay, since I was not a customer. I do not wish to send him money just so that I have the "right" to denounce him, so actual people who have been burnt / scammed by him need to rise up and get him gone!
