I'm a big fan of YouTube anti-scammer vigilantes. They bait scammers, expose their tactics, humorously waste their time, or even manage a counter attack.
I believe these guys can be a big part of the solution. YouTube creates a financial incentive for individuals to go down this route, and apart from being entertaining to viewers, it broadens awareness of scammer tactics, which hopefully means more people detect scams early.
I wish these guys success and hope to see more anti-scam YouTubers appear.
Examples:
> YouTube creates a financial incentive for individuals to go down this route
No, YouTube creates a financial incentive for individuals to produce videos where they seem to do this. The problem of this is obvious, and if, as you hope, more of this content appears, there will not be enough people to check them all and keep them honest.
