Wayne-Tec can continue to apologize all he wants but it's all wildly_fanciful_statement. The fact that he equates taking from a boardie who was here for due diligence on a book, to eBay's "Buy It Now" shows that he doesn't understand what he did and lacks remorse. I haven't followed too closely but from his posts the boardie did not appear to give up his interest in the book and was asking for opinions at the time of Wayne-Tec's grab.
With hindsight, the newbie might have taken more precaution as a stakeholder. On the other hand, I would have expected boardies here to help each other out... and respect certain communications as sacred. No one here ought to feel paranoid that a lead can be pulled from under them when asking for advice.
What to do now at this point? How about telling Wayne-Tec (and future Wayne-Tecs) to cut it out and show this board is not made up of wolves. Wayne-Tec's actions tell me he is far more of a speculator than a fan of comics. Nevermind the book he's going to steal may be another's hard to attain grail. There will be more flips in his future I'm sure. The only question is how many more collectors will he insult and step on for a few dollars more?
