tagwall prosecution

Passive aggressive employees who do not have enough work to do post complaints about the behavior of other employees on the tagwall (telecom employee webpage supposed to be used for outages). Such as: "I wanted to thank whoever "borrowed" my chair from my desk while I was on vacation. Most important, I'd like to thank them for also stealing my brown ACD hoodie that was attached to it. I really appreciate working with trustworthy employees." - Chair was actually in a corner with hoodie hung over it; thus never really stolen. There are also many posts about dirty dishes and such.
