The funny thing is, he could actually undo a lot of it. If Rob genuinely apologized to everyone he wronged, took responsibility for his actions, took a proper break to fix his life and mental health, changed his attitude, and worked to make it up to people, he could reclaim some kind of following.
It would never be as big as it used to be. I would not be a part of it. I'm sure none of us here would. But there are people who would forgive him. Good natured, albeit naïve people. And even his detractors would ease up on him over time. If he wasn't doing lolcow shit anymore, we wouldn't need to call him out for being a lolcow. I don't feel the need to attack someone who is genuinely trying to make amends and do better. Lolcows never do, which is why we never stop making fun of them.
And since Rob seems to be a true and honest lolcow, I don't think he will do any of this. He hopes that "time" and "lies" will heal all the damage he caused (cyraxx style). That is the easy, cowardly route he is trying to take. So fuck him. I don't feel bad if he is crying himself to sleep.
