The accusation that Leo left the forum due to low payrate is one of the most ridiculous ones I've heard.
I know nothing about this situation so there's that... However, if there's one thing I know about longtime Bitcoiners, it's that they know the value of BTC and when someone offers you some, a low pay rate can be easily acceptable due to the belief that Bitcoin will continue to grow in value. I doubt very much that a low pay rate is what made "Leo" leave the forum that has been a daily part of his/her life for so long. Especially when one has the belief that $100 in BTC will be $1,000 in BTC someday. This forum has been around for a long time. Many members are going to have health problems and leave in the future. It's the circle of life. In another 10 years it will be very common here I'm sure.
I'm in the same line of thought as you, Ok, Let's say that this is 30% truth, I doubt if someone like "Leo" would because of low pay rate present health issue as a reason for him to leave the forum when he can quietly leave the forum without stating his reason for doing that and no one would query him for doing that, To me leaving the forum because of low pay rate is far from the real reason.
