I know some scammers are intelligent people who read a lot and can discover this forum from their research while trying to gather information, but it is possible that some of the people we are referring to the forum are scammers, and we now also have to be careful of the people we refer to Bitcointalk.
Avoid referring the forum to friends and even family who we know have tendencies to become scammers, have affiliations with any known scammer, etc.
Haven’t you also have a thought that the scammers are or might be regular members already in the forum?. The forum allows the creation of alts so once a member decides to go into scamming they can just easily create another account and advertise their products. So to me, the biggest number of this scam accounts are members that are already here
Also I don’t second the idea of you not guiding people to the forum because they will scam. This forum could be the only place they get authentic information about cryptocurrency and should they later involve into scamming you can as well report the account
