..... why give default trust to people who won't be really looking for scammers? I mean they'll be busy with their business. Are they trustworthy though? Yes .......
You are missing the whole point, this post opposes giving trust points to scam busting. Scam busting is ethically wrong and is a short cut to gain massive amounts of trust without doing anything other than trolling around playing pretend cop.
Users should be encouraged to trade with even the most trusted people like Theymos / John K
with one eye opened. The moment you introduce the age old 'reference' system it is a cocktail of disaster because then you are simply encouraging people to blindly trust the 'most trusted' person - who could turn out to be a scammer. Example : Tradefortress.
