The National Science Foundation is funding the “Truthy” database, intended to detect “false and misleading ideas,” "political smears," and other "social pollution” in online political activity. Researchers at Indiana University have received $919,917 (so far) for this project. The resulting open-source platform will be made publicly available, including via a web service open to the public for "monitoring trends, bursts, and suspicious memes.”
According to the grant, “This service could mitigate the diffusion of false and misleading ideas, detect hate speech and subversive propaganda, and assist in the preservation of open debate."
Yes, you are publicly smearing a politician if you disagree with the legislation they have proposed or passed, or just disagree with the politician. Hell, why aren't you voting for him again?
