I would not rank the catbox squatter in the top ten.
His only strong point is the sheer volume of his posts, dozens and dozens per day, and every year he gets votes on that alone.
His weak point is that out of dozens, hundreds, thousands of posts you cannot find a single one with a shred of entertainment value.
He is a constant Stalinist shower of hate.
Dull, blank, faceless, boring hatred is the squatter's stock in trade, with not a glimmer of imagination or flair.
The DUmp is full of volatile, seriously ill lunatics who have the potential for really funny crackpot outbursts.
The squatter is just boring.
