If someone WANTS to scam. They will do it no matter what. If the requirement is 1000 posts people will spam until they get that many. If they have to have 30 day old accounts they will create 10 accounts and wait a month for them. More restrictions also means that people trust others more easily thus an even better opportunity for a scammer. I think it's right the way it is. You won't stop it and you are only making it difficult for others to get access to trading. If you don't want to lose money, dont trade on black market forums at all. If you are willing to take a risk go ahead. No one can be trusted no matter how many FB he/she has gained. It's obvious since there are people who quitscam and such. People are greedy that's why the world is what it looks today, capitalism everywhere. If someone wants something and sees an opportunity they take it. It's sad that people scam but it's nothing you can change.
