FWIW, it all results back to the same person who has been doing that stuff for ages. This board member has made it a point to go on +1'ing sprees of our more conservative brethren, often times just making their way down a thread and +1'ing every thing that's said. They did it for Ric and they're doing it again now.
I don't know if they were once a P&R regular or not. They're currently not from what I can see. But, they take it upon themselves to be a +1 advocate for conservatives.
I don't see any good in outing the person. I say all this mainly because people sometimes think a 'main' account is +1'ing a sock account, or something odd like that. It's not the case here.
