Are there currently any posts about this on her forum, or all they all officially deleted?
Also keep in mind that most of the people who fund Peggy seem to be non-English speakers or spoiled little teenagers, so always remember to keep your rebuttals simple. I've been using the "Peggy is mean!" approach over the "Peggy's actions are illegal and unethical" approach. I mean, clearly anyone who has been a Peggy fan for more than five minutes is dumb or doesn't speak enough English to know what we're yelling at them.
ETA: Aww, I got IP banned. I was thinking about PMing her about this:
While the methods I use are my own "trade secret" the way the file is made leaves markings are irrefutable evidence she generated the final output of the two pay hair file I examined with my plugins. And the license terms very clearly prohibit commercial use.
She can claim she is using something else, and it may be true, to the extent she may be modelling with maya. But the final file was created with one of my plugins, or by code stolen from my plugins. Her rattling statements about insult, libel and attack are nothing but bluster and bravado. She is on the wrong side on this issue.
