There is no reason to believe this:

>25% of cast votes result in XP.

It's not difficult to see how this accumulates in thousands of XPs over the years.

And I find it disturbing that monks who turn up regularly to read and cast votes are doubted.

Just because they don't fit into some simplistic model to rank postings, it must be their fault?

exactly!
