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.
I've seen a lot of accounts banned due to fraud, including those from higher ranks as well as beginners. I'm sure that these individuals would have made another account and invited their friends here, so I don't think the problem of scammers is new to this forum.
Avoid referring the forum to friends and even family who we know have tendencies to become scammers, have affiliations with any known scammer, etc.
You make a valid point, but not all of our friends or family we know that they are into this act, so what do we do when they ask us to link them to a website where they can learn more about cryptocurrency? Because in my view, this is the best place to learn about cryptocurrency.
