My brother seems to not care about his online privacy. He registers to services too easily without pondering, he’s not outraged we need a fucking account to use a vacuum cleaner, it seems he doesn’t care about all the potential risks of having videos of our indoors saved in a cloud. I don’t have strong arguments to convince him that privacy matters other than “if someone gets that, you could be in trouble” and “it’s like having someone watching you h24” and so on. How can i persuade him?
Just try to find out his old Xbox comments or wherever the heck he used to post on forums. Make them appear on the Google search with his name in quotes, and tell him that employers or his future date can easily spot his poor behaviour as a part of background check. Use Bing for better results. Google hides some result, but not Bing.
