defcon23 is the blackmailer in this matter, and he has a history of blackmail.

blackmail:  to force or coerce into a particular action, statement, etc.

I left defcon23 proper negative feedback after he was caught in a escrow scam.

He then left me negative feedback calling me a scammer.

He then sent me many PMs saying he would remove his feedback if I removed mine.  I finally had to block his PMs.

Now he did the same thing to Lauda, removing his lying feedback only once Lauda removed his feedback.

I have no idea why Lauda would leave that blackmailer POSITIVE feedback while he continues to insult Lauda.
