While there are plenty of scammers and their methods are pretty obvious to most members who have been around for a while, there are probably more newbees who have no idea that their requests are considered "scammy" when they are just exploring.
I understand what you're saying, however, from what I've seen in this subsection here over the last year or so, it's almost all scammers. A lot of them follow the same formulas - it's obvious what they are after from their insincere posts in the other sections. (I haven't seen TC "randomly" doing anything, btw.)
That being said, if you want to politely explain why they are acting in a suspicious manner every single time it comes up, be my guest. I have taken that approach on several occasions.
The flipside of your argument against "scaring away newbs who don't know any better" is the "less discerning lenders that don't know any better" who might take a closer look when suspicious behavior is identified when they see the thread.
The fact you were scammed by people with a high post count is not a counter-point. It means we should be even more on guard. Post count is certainly not enough to trust someone. I personally wouldn't lend to anyone I hadn't met (or didn't at least know someone I had met.)
