Have you thought of the possibility that these folks deliberately took time off from FR?
Some quit posting because they got butthurt when they posted something stupid and were called out on it.
Some quit posting because they were called the aholes they were for being extremely crude and rude towards others here on FR.
Some quit posting because they challenged JR and then went to other so-called “moderate” sites where about all they did was complain about FR.
Some folks quit posting due to the abrasive and confrontational nature of some FReepers, crossing the boundary of good etiquette and courtesy.
Some go dormant because something in their lives has become more important than sitting on an on-line forum.
There are many reasons why...I even took over a year off from posting because I really needed to...a reset.
I’m not a troll.
I sometimes have web access, sometimes not.
I have no web on laptop only cell phone.
I have remarks to make, sometimes not.
I have $$ sometimes, sometimes not.
I am not a troll.
Even I was, I would only troll on the left.
