For instance, the "Tax Delinquents for Recall" category lists 571 petition signers who are in tax arrears. One category lists 444 sex offenders and another lists Democratic political donors.

Another page on the site allows users to search petition signers by offense, everything from homicide to speeding.

Limbaugh said the website was the work of an "anonymous researcher."

"Thanks to his hard work, we finally know who is not paying their fair share of taxes in Wisconsin," he said.
