No fap is something a bunch of dudes who have no control over their sex addiction came up with, and pushed on everyone else. As long as fapping isn't causing you to destroy your relationships or lose money because you can never show up on time (or worse you feel the need to do it at work) you have no reason to do no fap.
There's no way you can even verify the dudes who promote it are following it, they could be just posting YouTube videos for money, busting, and laughing at the dudes following their advice behind the scenes.
