That might be the reason. I've noticed since his last rejection video there has been less of his "yes men" commenting and more people making jokes at his expense. It could be a combination of that and being rejected harshly, though we may never know.
I don't understand what he was expecting. I mean, I do know he's been bullied in the past back in high school, but how are you going to let people on the internet get to you so easily? He shows the most vulnerable side of himself yet he's surprised people are attacking him for it? Hell, he's started to delete my comments on his previous videos as well and I've been quite tame with my words, compared to when he came onto my channel to call me a "bitch ass nigga" and told me to "drink diesel gasoline". He complain about cyber bullied, but how many times have he harassed someone incessantly over minor offenses? He's always the victim. The poor, innocent nice guy.
I honestly wouldn't be surprised if he kills himself or goes on a shooting rampage soon. I'll give him 5 years at the most unless he changes his mentality.
