@monsieuricon To compare the waste of processor cycles, to public resources like a forest is questionable, as a processor doesn't wear any more from processing 1 billion cycles a second than 3.5 billion a second, while a forest runs out of trees very fast and likely forever.

It seems the only effective method to curtail that would be get your lawyers to send the scrapers Cease & Detest letters, noting that you're not clueless and know that they're clearly planning on infringing the GPLv2 and you'll be enforcing your copyright if it happens.
