It's not that.
The reason so many PF posters are in the bottom is because we post a lot in a forum where we're the only ones around. There's what, about a dozen of us that post there regularly? Let's be generous and say 2 dozen. Of that number, generally half will agree with you and half will disagree. So at best you might get 12 likes on a truly outstanding post. You're lucky if you get 1 or 2. Plus, we post there A LOT. Look at the top 10. Half have under 160 total posts and I'm the most prolific poster there (barely making the cut at number 10) with 2,990 posts. Look at the bottom 10. The lowest number of posts is 3,409 with half having over 8,000 posts. Posting a lot drives down your ratio. We might post 10 times in a single thread. That's generally not going to get you 5 likes.
In the main forum, you've got two or three times as many regular posters and they ALL love UF and hate FSU. A truly outstanding post could garner over a hundred likes. If you're lucky, you'll break 20.
The only reason I'm in the top 10 (barely) is because of a few posts in the main forum that got double digit likes.
URG is a good poster. So are you, so is Coach, so is L-Boy, etc. All the PF posters aren't at the bottom of the list because people don't "like" you. It's just the nature of where we post and how we post there.
I bet if you just looked at posts in the main forum, the denizens of the PF wouldn't be ranked so low.
