After reading the guidelines, the supplemental posts, and going through more ads than I ever have at one sitting I'd have to say this was the correct place to "ask for clarification on the guidelines as they are written. (As opposed to RTM or PM)
I certainly saw no real issues with the ads, but if the guidelines state - and they do - not to use "code words" then the instances of violations are overwhelming. If these are to be allowed - and again I hope the follow on references stand and they are - a slight modification to the "guidelines" would appear in order. It seems ridiculous to say "here are the guidelines" and then follow up with "caveat posts" on a case (new provider) by case (post here suggesting violations) basis.
Crap - did I just agree with the op?
