Here's hoping Hasbro starts targetting those fan forums that are promoting and encouraging these KOs. They might not be the source, or creating demand, but they are generating a 10-fold increase in the demand through the hype and support of KOs. That demand has created the need for more KOs, and how many new fans shopping on ebay are being ripped off because they are buying what they thought was legitimate nostalgic product?
I wouldn't be surprised if this action by Hasbro was due to a growing number of parents or kids have been contacting Hasbro Customer Service with complaints of quality issues or requesting replacements for what they didn't realise were KOs. As opposed to them losing any money from illegal reproductions (which they wouldn't be if they are not even available legitimately anymore).
At least we can be proud to be the one fan forum in the world that actually discourages the promotion of KOs (you can still buy whatever you want privately though).
