Martin Shkreli, the so-called "pharma bro" and former CEO who was recently convicted on securities fraud and wire fraud, has been recently buying up domain names of journalists that appear to have written critically about him.

The list includes Rob Beschizza of Boing Boing, Meg Tirrell of CNBC, Maxwell Tani of Business Insider (who reported Tuesday about the domain buys), and our personal favorite: trashythecat.com.

In at least two cases, he has used those domain names to create websites that mock those reporters.

For instance, MayaKosoff.com, named for a reporter at Vanity Fair, simply reads: "Here we honor one of the most vibrant Social Justice advocates today."

Shkreli has been offering to sell at least one of the domain names for thousands of dollars. In a public Facebook post, Shkreli has offered to sell the EmilySaul.com domain for $12,000. Saul, a reporter for New York Post, declined to comment further on the incident.

"Unfortunately, due to company policy, I'm unable to answer any questions and must decline comment," she e-mailed Ars. "Best of luck with your story."

Kosoff told Ars that she had not received an offer to sell back her domain, however.

Shkreli did not immediately respond to Ars’ request for comment.
