Most of the possible problems would be the same as selling anything -- from books to babyclothes to gunsights to jewelry to Magic The Gathering cards- as a new seller.
Your low FB score makes you a target for scammers.
You would tend to be selling into a high testosterone demographic, and that has its own set of problems.
You are selling a used product, with no warranty from the manufacturer.
And if it were used in the field, there could be unimportant scratches that the above mentioned testosterone-charged scammers would whine about.
And Paypal would hold your customer's cleared payment for 21 days against your good performance.
I don't think the sight would be a problem,as such.
But you may at this point, find it easier, faster and more profitable to use a local free online classified ad. Cash on pickup, meet at Timmie's. (Try the Nutella Bites. They're great.)
