The timing just happened to be coincidental with the mixer ban. Let's not indulge ourselves in conspiracy theories now.
Let's be honest we can't know 100% if o_e_l_e_o really left the forum because of his health issues or for some other reason. We can only make educated guesses based on his post history and since he looks like a genuine a person, I'd say the chances for him telling the truth are higher than 90%. Is it 100%? Unless you know him in real life and saw his hospital records, you can't tell that and I think nobody here knows him in real life.
90% is what you would give to most of us plebs if one of us was to mysteriously stop posting all of a sudden. I'd say it's closer to 99%. Using
"Nines" nomenclature.
Besides, pretty much every serious online activity pays more per week than whatever you can make on the forum. It's called beer money for a reason.
