restriction of sale posting

[KALYANPRODHAN]

Anwar sir,
Can we distinguish among user about seller properties so that one of them (seller)cannot post in another's sell thread.
However the problem is that whenever a modeller want to sell, he will be converted to seller and the rule will implied to him for some months. And the seller have to continue with his status if he  will sell continuously. However they all can post in other thread except sell - sub forum. At least leg pooling may be reduced. And the thread originator in sell sub-forum will award automatically the seller, seller status. Moreover, post/week in sale thread can be restricted for them. They can use other site instead of ours for lots of posting in same thread to highlight / controversy with another account (Against rule if both are same, IP tracing can be introduced for sell thread originator only ). Reputation power and/or posts can be considered while putting seller restriction to them (Like classification of vender).
Of course, the problem is they then post in other sub-forum, but the chances will be less and the moderation work will increase some little bit.
Please think over it to keep clean.

Though this is against flourishing of LHSs market. But patience is the main criteria to become an aeromodeller or even modeller.
