That's not quite right. I believe you can advertise an item for sale here on this site in the classified section for no charge but it has to be approved by a moderator beforehand.
I'm familiar with sites that charge a fee to sell in the classified section. Whether I agree with that policy or not will remain unsaid.
Being a paid advertiser here myself, I try, at all times, to adhere to the User Agreement plainly spelled out in the FAQ section. I suspect very few posters read that section. The owner of this website is an individual of good temperament, easy to deal with and leaves daily administration up to Tomo and Pigger, who, at least in my opinion, do an excellent job.
One thing I make a habit of doing is reading the user agreement on any site that I register on. That way, you understand the boundaries in which you can operate and minimize your risk of getting banned (which can be embarrassing). Not to say I haven't peed off the Mod's on this site before because I have. Occasionally, everyone oversteps their bounds, it's human nature.
