I don't know why, but I was under the impression that the decision to disallow guests from viewing feedback had something to do with cases where an employer or something is doing a google search on a potential employee, and ends up here, "Biggest Shitboi on forum, Skemmd my Grandmum for 5,000 BTC", "Guy sucks, l0l" etc feedback.
Again, I don't know if thats correct but something is telling me that was a consideration, though I don't have a source. The obvious hole that sticks out in my mind, is that there are only a handful of people here who used their real names, or have published their real names. I can't shake the suspicion that trust was only meant to be a factor in sections where it might possibly matter, and between members who are at risk of doing some sort of trade, at least partially for that reason. I don't think that conducting business with guest users was a consideration. How would you exchange PMs arranging a trade without an account?
Yes, but many of these people now invite you to discuss the trade offsite like at telegram or discord.
