I agree with you, ginny. Sure, TE operates these forums and sets the rules as to what is and is not appropriate. But . . . while some things may be unambiguously prohibited, there is necessarily a fuzzy--and pliable--boundary between appropriate and not appropriate.

I don't think it's inconceivable that the administrators would, in part, look to the forums' users to help determine where that boundary is. And what is permitted may change over time.

What is and is not appropriate for the FS forum appears to be in a state of flux right now. I don't need another bike but I will still check out what bike4ever is selling. And her listings are almost exclusively women's bikes or bikes in small sizes, which seems appropriate for this site.
