Detect Russian visitors to block them and protest the war in Ukraine

Detect Russian visitors to block them and protest the war in Ukraine launched on February 26, 2022 with 55 votes, #906 of 2,645 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 4 years on.
