Hacktivism is a type of activism that uses computer hacking to promote a political or social agenda. While some believe that hacktivism is an effective way to bring attention to important issues, others believe that it goes too far and can never be justified.

One example of an effective hacktivist campaign is #OpIsrael, which was launched in $2012$ in response to the Israeli government's treatment of Palestinians. The campaign succeeded in taking down over $7,000$ websites and exposing sensitive information about Israeli government officials.

However, not all hacktivist campaigns are so successful. In some cases, hacktivists have gone too far and caused harm to innocent people. For example, the campaign #OpFrance, which was launched in $2015$ in response to the Charlie Hebdo terrorist attack, targeted a French newspaper that had nothing to do with the attack.

The campaign resulted in the newspaper's website being taken down and its staff receiving death threats. Overall, whether or not hacktivism is justified depends on the goals of the campaign and the methods used. If a campaign is targeting innocent people or causing harm, then it is not justified. However, if a campaign is raising awareness about an important issue or exposing wrongdoing, then it may be justified.
