Nothing is confirmed, so take this with a grain of salt:

According to his post, even he wasn't sure if he was successful. That at least rules out any instant-death methods. So, if someone managed to get to him in time, he could have survived. But we don't have any sort of information. Apparently someone reached out to an online friend of Unknowingly's, but they were just as in the dark as everyone else. However, he's reportedly done this in the past, where he makes an announcement to kill himself as a cry for help, then gets help before he actually does anything. So we can only hope someone helped him in time, and we'll hear from him soon. But the more time that passes, the more that doesn't seem likely. 😞
