No support, because there is the classic ./ignore command, and hackusating most of the time might be false, but this erases the scenario in which the recipient actually hacks, and the person's claims are valid. Uploading a video takes time, especially for me because of my bad internet, so to show proof would be time-consuming and infuriating. As well as the hackusator might be trying to notify the other people around that this person hacks. It sounds like this Long_Island_Pat might be a cynical person so I would just ignore him.
