Why must people insist on deleting their whatever account? Like making it such an ultimatum, and fierce stand. Just get over yourself. You can still keep you account, check in when you want to for the important stuff, while it may be seldom. But there will be something important that you will likely miss, like a friend dying, or something else. You can also still keep your account and not even need to log in. So what's the big deal? Why make a fuss?
It's because people have no self discipline, and are so gullible to being bored that they fall into weakness. The stance to be made is plainly resistance. You don't need to get all huffy puffy. And if you want to disappear, just go. You don't have to make an announcement of your disappearance. Fucking drama.
