The staff of the website wesearchr.com, which bills itself as a platform for “crowdfunded journalism,” have raised more than $5,000 as a reward for the identity of the man who punched alt-right leader Richard Spencer at the inauguration of Donald Trump on Friday.

The site is now also attempting to raise $250,000 to sue Twitter, which has banned the site’s account following a tweet about the bounty.

Under the headline “Expose The ANTIFA Who Sucker Punched Richard Spencer,” the man is referred to as a “domestic terrorist” and donations are sought to increase the bounty on his identity.

“Antifa” is the alt-right term for their opponents, short for anti-fascists.

The bounty appears to have been posted shortly after the incident, and on Tuesday the site added the disclaimer, “Information on the suspect who is the subject of this bounty will be immediately forwarded to the appropriate law enforcement departments. As our terms of service and disclaimers state, this is not a call for any vigilante justice, libel, or other illegal action.”

Other “bounties” on the site include those seeking proof of election fraud, proof of the so-called “pizza gate,” and a DNA test for African American journalist and activist Shaun King.

Spencer coined the term “alt-right” and became well known for saying “Hail Trump” before a crowd of people giving Nazi-like salutes. He was assaulted Friday during a television interview.
