Well, granted that allowing members access to the market forum after a initial number of posts may not be a perfect idea, BUT at least it does act as a form of deterence for those self-biz owners who are looking to make a fast buck here.
NO form of prevention can be 100% fool-proof. No matter what the admin implements, some bugger will eventually find a way to go around the system and exploit it. But currently the idea of allowing ppl access to the market forum after a ficed number of postings, seem to be the most logical and cost-effective way of wedding out these cheapskates.
Of course the best way is for Chin Leng to delete the thread and revoke the thread-starte's membership immediately but this too has its own difficulties. One, what's stopping these people from re-registering another nick and doing the same thing all over again. Two, it's exhausting to police the forum 24 hours, every hour, every minute, every second. Chin Leng could hire some help to assist in cleaning up the forum but this will definitely increase the operating costs and overheads; and this may 'force' Chin Leng to charge an annual memebership fee to all of us if we want to post on this forum. Is this what we want?
Hence, I really believe the best way thus far is to allow sellers to advertise for their own personal stuff after posting a minimum number of posts. This is to weed out those cheapskates like ROSEBUD. And of course, the next best way is to ask all forum users to boycott this self-biz 'cos to borrow a quote, if the buying stops, the selling will too.
