The anonymous person who posted the link to the anti-PRT site ("PRT is a Joke") is Ken Avidor, who is a rabid anti-PRT extremist. He spends all of his free time hunting down any discussion of PRT and injecting his anti-PRT propaganda. Most of what he presents as "evidence" is nothing of the sort - just various political rants and conspiracy theories.

Take everything this guys says with a grain of salt.

For a more balanced discussion of PRT, see the PRT Wikipedia article.
