Flea, nobody hates Joe. There's nothing there to hate.
Joe posting on a forum is on a par with getting a Publisher's Clearance sweepstakes envelope in the mail. The title can be a hook but you know you'll gain precisely nothing by opening it.
The man (and I use the term loosely) is about as substantial as a wad of snotty Kleenex lying on the sidewalk at the mouth of some dark alley after an evening rain.
Could be Joe is disliked because of his propensity to foment boredom with his incessant and ubiquitous cross-forum drivel.
Just a theory.
