I have sent the following to him, rejecting his offer to "forget the whole thing:"

You falsely accused me of interferring with your bidders; you had no bidders; you sent a malicious post calling me an obscene name; and you made a veiled threat to destroy my computer. If you 1) apologize in good faith for that post, and 2) correct the misleading description of the chip, I will forget about this. Otherwise, I intend to send my original post; you obscene response and this message to EBAY.
