Unless you pay to be a site supporter, you are required to have 50 "quality posts" before buying or selling anything through the classifieds.
Well technically you're supposed to have the 50 posts before you can "participate" in the classifieds, not simply buy something listed there. Because OP didn't send a PM or post in the thread he likely used an email address or phone number posted in the ad. So technically he did not "participate" in the classifieds, but outside of the parameters of the site.
I'd hate to encourage someone to plead ignorance, but in this case I'd put the infraction on the person who posted the ad. I have a hunch that I know who it was, because there is a flipper that is notorious for including his phone number in his ads.
