I use multiple browsers. I tried switching solely to duck duck go and/or Firefox but can’t help but still use chrome. Chrome is not very “trustworthy”, of course, but good luck searching for btalk stuff (or damn near anything for that matter) via the duck duck browser and others. If I want to find “ satoshi escrow bitcointalk.org post” , chrome brings it up top link. Duck duck’s first few results are of Craig Wright claiming that he, “Satoshi” , never even posted on bitcointalk.
I and I’m sure others active on the marketplace boards would like to have their full profile viewable with out having to log in. As a “collector”, I buy/sell/trade on all sorts of sites and forums. My eBay and btalk user profiles are a way to help “prove” my trustworthiness with a potential trade partner. This is my selfish reason.
Non-selfish reason: Scammers need to be exposed. Plenty of scammer companies have profiles here. Imo it’s important to expose them as much as humanly possible. A public forum profile trust page is one way to be sure!
(Edit: I too have many times wished the same for viewable merit as well).
