Reactions were only added to the forum a few years ago - the ratio of reactions to posts reflects this. Maybe it was just before you became a member?
If you want to rank members you can't use reactions as many members were here before reactions started.
There is also the points system which recognizes longevity - e.g. "Ancient"
A power ranking based upon recent history would work though.
I'm well aware of that, which was also why I've suggested I shouldn't do it, as I was visited the forum occasionally in the years before I joined.
