It could be argued , although I am not looking to argue anything , that even people who sign up JUST to advertise something , may actually benefit the membership if even one member wants whatever it is they're advertising .You are not getting it are you? It is precisely to stop people JUST posting in the clasifieds to get free advertising. What is annoying about that?
You are not banned from posting on the Forum and contributing and as the minimum post count was decided upon by Forum Admin it is hardly arbitrary.
I remember finding myself in exactly that situation some years ago when I advertised my W124 E250D in the classifieds on here , and another member ( Silversaloon ) suggested that I advertise the car on another forum set up by Veg Oil fuel / biodiesel enthusiasts that he was a member of as he thought there would be people on there keen on the car .
I did just that , explaining that it had been suggested I post the car there as it was the type of thing their membership might be interested in , and got a number of snippy replies before SS stepped in and said he'd directed me there ...
You just can't please everyone .
I eventually sold the car on here to another member .
