I advertised my car at a 3rd party classified website. Bring a Trailer (www.bringatrailer.com), without any content of their own. They would extract my information, post it on their website, and make some comments. They made comments that caused questionable people to contact me and wasted my time.
It turns out, they wanted $100 to post my car on their website. It makes no sense, there are many popular sites out there that allowed free postings.
--Sounds like a Scam and Fraud.--
