Don’t take this the wrong way, but why? I have seen over a half dozen instances of other members doing that and in return getting retaliatory feedback and that feedback standing. I understand the mods position of being neutral, so in my opinion the feedback is just to acknowledge a transaction went smoothly. Why run the risk of getting negative feedback yourself? I’ve had several instances of what hardboiled has experienced (especially since arms list went to pay to play), but I have not left feedback out of fear of retaliation.
Just my $0.02.
