Today, April 22, at least 373 websites have joined Anonymous in their protest by shutting down regular activities and displaying an anti-CISPA banner.

Many of the sites that have joined the protest are run by activists, but other organizations are also on the list published by the hacktivists.

However, unlike with the Stop Online Piracy Act (SOPA) blackout that took place last year, this time, none of the major companies have announced their participation in the protests.

Last week, the Cyber Intelligence Sharing and Protection Act (CISPA) passed the US House of Representatives for the second time.

One thing that triggered numerous protests was a statement made by US Rep. Mike Rogers, one of the controversial bill’s most vocal supporters, who said that those who opposed CISPA were aged 14 and lived in their basements.
