I think two letters, FS, added by the original poster to the very beginning of each FS title would really simplify things for both the readers who seemed bothered by FS adds and those that are seeking to learn more about that product. Learning, after all, is why we are here more or less.
I.e. the only time a FS ad bothers me is when the the title interests me as a topic, but OP hasn't noted it's for sale in the title. Not being able to comment within FS threads has been disappointing when it comes to learning to say the least.
I have forgotten about the rule on occasion, but I only asked questions I felt were knowledge based anyhow; no deep guilt there.
I guess it's time reread the TOS too. I don't know if the rule applies to Wanted also. I recently posted to a wanted ad because Ive seen so many comments and questions in those the last year, I figured it was ok....but admittedly didn't actually look (I tried, but can actually very seldomly use the upper left menu; it rarely works for my Android browser [ I'd need four browsers to get all functions. None work every feature here. I stick with the best ones for my reading/posting])
Working a deal out should be private; no argument there. I don't see much difference in alerting someone to an email issue in a FS ad or in another thread, which is what happens quite often.
As a fan of transparency in advertising, coy titling of a FS ad is extremely annoying to me. "Ha ha, made you look" must remain sparse to retain it's playfulness. (wolf...wolf....wolf...doesnt make you "foxey" 
)
I know it works to get a potential customers eye, but I refused to work for companies chose this route as thier norm and hate it much more when indivuals choose to play "the game" this way because in note lacks of conscious to me. I pass unless I already figure I know how the person really conducts themselves already.
It is not the best of reflection on an individual seller imo. If you are quick to try and fool me in an ad; will you be trying to fool me on the deal?
Not to mention if I start a new topic to cover a question, it's often ignored by many. IMO mainly because of the ad with similar title preceding it. (These questions were the ONLY posts I made not ever responded to......likely because the people who could have answered for sure (the FS OPs) never even saw it.)
I'll doubt I'll ever budge on this outlook; thirst for knowledge being at the forefront wins out for me most every time.
