Hacker group Anonymous also joined in the protest by posting messages against SOPA on its websites.
Social news site Reddit said on its website that it would be closing down the site for 12 hours to protest SOPA and PIPA. It had said earlier that it would be closing down the site from 8:00 am Eastern time.
Twitter has however not participated in the protests. "Not shutting down a service doesn't equal not taking the proper stance on an issue", said Dick Costolo, CEO of Twitter, who in an earlier Twitter message had said that "closing a global business in reaction to single-issue national politics" was foolish.
