A website that promised to unmask critics of conservative activist Charlie Kirk took tens of thousands of dollars in cryptocurrency donations before going offline, according to a report.

The site “Expose Charlie’s Murderers” was launched hours after Kirk’s assassination on September 10 and pledged to name and shame those who spoke out against him to pursue “the largest firing operation in history.”

It asked supporters to contribute toward “a highly sophisticated enterprise system that will be impervious to Leftist attacks,” and directed them to cryptocurrency blockchains, the technology behind bitcoin and other cryptocurrencies, according to Drop Site.

The website’s anonymous developers raised more than $30,000 from supporters between September 12 and 14, according to the outlet.

Now the domain www.charliesmurderers.com has gone dark.
