Should I mention this in feedback?

[nzoomed]

Something I have learned on TM. Never poke the bear unless you have cleared it with the mods first. And I have poked the bear several times, with TM backing me up if things got nasty.

I always got the impression TM never took sides.
Thankfully ive never really had to deal with anything major.

Once I did place a red face on a buyer after numerous emails and no contact, then once I placed the negative feedback, all of a sudden I hear from the buyer asking why i placed a red face and was all apologetic and in the end the trade went through, so some times it works with time wasters.
One other time I never heard back from the buyer and then I get a blue face despite me emailing them multiple times, despite me not even leaving any feedback.
