I've thought of this option, and I do think it can be helpful.  It would be nice if we could add a custom depth to each of inclusions, but like o_e_l_e_o mentioned, it would add complexity to an already complex system.  Maybe a custom depth setting can be implemented as an option, and not a requirement.




This is one of the philosophical debates about the current system; is it a "trader" rating or a "trust" rating?  Should it be limited to those who've completed trades with one another, or is more than that?

It's my opinion that the trust system is designed to be more general and broad, and therefore more useful than merely a "trade" rating.  There are many attempted scams that don't necessarily involve a trade of goods or an exchange of currency.  And anyone could simply start trading in rinky-dink transactions that amount to only a few dollars and still earn a high trade rating.  If it was limited to only trades, then every one who dealt with CanaryInTheMine would like a trusted individual.  We know that's not necessarily the case.
