A virtual sit-in is a form of electronic civil disobedience deriving its name from the sit-ins popular during the civil rights movement of the 1960s. The virtual sit-in attempts to recreate that same action digitally using a distributed denial-of-service attack. During a virtual sit-in, hundreds of activists attempt to access a target website simultaneously and repetitively. If performed correctly, this will cause the target website to run slowly or even collapse entirely, preventing anyone from accessing it.
