Eric Wang in WaPo:

Civic-minded citizens of the District: Think twice the next time you write a blog entry, post on Facebook or Twitter or attend a meeting or rally to support or oppose a ballot initiative. You could be required to register and report with the city or else pay a large fine. The Office of Campaign Finance(OCF) at the D.C. Board of Elections dropped this end-of-the-year bombshell in an enforcement proceeding arising from November’s election, in which District residents voted to legalize marijuana.
