While there is no public news regarding a person named Nick Cockman being "hacked," there are several notable individuals with that name, including a landscape photographer and a marketing professional based in the UK.
While I couldn't find any information on Nickmercs being hacked, I did find that he has been involved in some controversies throughout his career. In 2020, he was accused of using a racial slur during a live stream, which led to a temporary ban from Twitch. He has also been involved in some public feuds with other gamers and streamers. nick cockman hacked
