While I have not been a "victim" of it personally, as I generally ask or offer my trades / sales for under market value strictly in the good spirited nature of supporting the Hobby, there seems to be a good bit of what I term as the "Trade Police" going on the swap / sell board. One person offering thier opinion on another's trade worth or value, rather then actually offering a trade. IMO, an item's worth is what a person is willing to trade for it. It may not be worth it to you or me but it's not our place to point that out. The trade / sale market will bear that out. I'm not sure where or when it started but it seems to be increasing. Maybe that's why I don't see some of the "long-timers" on here as much as I used to. Slight Rant Over.
