"There are page upon page upon page of these products," FBI agent Elliott Peterson said during a presentation at the BlackHat conference in August.
Many of these DDoS-for-hire services offered through Hack Forums look professional and appear legitimate but advertise the capability to take down websites and servers, Peterson said at the time.
Legal experts have also said that Hack Forums can be held liable for promoting DDoS attacks if there's evidence proving illegal activity.
"It comes down to what's actually happening, and not what's just being advertised or described," said Marcus Christian, a lawyer for Mayer Brown who specializes in cybersecurity. He questioned whether Hack Forums was financially benefiting from the alleged DDoS-for-hire providers.
The Hack Forums site had said that for $80 a week, it would promote sellers' listings in the Server Stress Testing section.
LaBrocca said on Friday the section will never return, even when the "drama" dies down.
"I'm personally disappointed that this is the path I have to take in order to protect the community," he wrote. "I loathe having to censor material that could be beneficial to members."
In an email, LaBrocca said Hack Forums was similar to Twitter, Github or Reddit with its approach to content. "The content on the site is member created and reflects the topics they are interested in discussing," he said.
