My opinion: Let whoever wants post as much as they want with no prerequirements. Ive been a member of a few other forums for over three years and dont have more than 300 posts total in that time span. Yet some kids who bought a ball or gecko from the local petco have that many posts in a month. Quality (posts) and quantity are two different things. If the mods are aware someone is scamming then of course they should pull the ads and ban the seller. If someone isnt well know its still possible they produced a quality animal and should be able to post/ sell it without any special rules. Buyers can ask sellers questions, check the BOI, etc etc, let them decide how they want to spend their money with the most available(legitimate) options).
