Well I don't really have an opinion on leaving those companies negative feedback because I know nothing of the circumstances, but what I want to know is, Mabsark, do you feel leaving retaliatory negative feedback to der_troll is appropriate considering yours carries so much more weight?
At the time is was left they carried equal weight and I reached out to der_troll immediately via PM urging him to reread the thread and reconsider his decision. Until he responds to me, then yes, I do think it's appropriate.
Would it be appropriate for me to change that feedback just because der_troll's trust level changed though?
Given that the topic of this thread is your feedback against those companies, and that it depends on circumstances changing (being able to prove they aren't a ponzi), I would think you would jump at the chance to show you are trustworthy and fair with your ratings, and that you do intend to change feedback as circumstances change. Being in default trust network doesn't mean everyone trusts you, just that the one person who put you on their list does.
