No disrespect to anyone. but the Market section is the only thing many users (including me) come to this forum for. Evidently because we were tired of all the haggling and trolling on sites like olx and quikr. Even though there is no accountability over trade and monetary risk involved here, People still trust this site because of its long standing presence.
I'm sure the 25 posts thing was implemented in good faith to discourage trolls, but new members just see it as an impediment to get to their sales and shit post. Mods have a tough time regarding all this im sure, but no matter how many such implements are used, those who intend to troll will keep trying to no matter what.
