This is one of the worst logical breakdowns I have ever attempted to understand. Your first point is entirely based on your personal stereotyping i.e. "old people can't internet, lolos". 2nd point, she is a motivated and well educated person who is not risk adverse, specifically with money or power. Your 3rd point is a just an open ended observation "hard to believe Ghislaine could be the brains of the operation", she is accused of being part of a 20 year conspiracy that was actively trafficking in underage women (to speak nothing the financial or blackmailing activities), if any of that is true she is an accomplished criminal and villain spanning decades without so much as a speeding ticket...running an active reddit account would be within her capacity to plan and execute.
