Players are kbinter and Fenix5.
It was a normal game, but someone pointed out that kbinter's reviews said he PGA'd with Fenix5.

Upon checking, it was correct. kbinter had multiple reviews stating that he PGA's with Fenix5. Further, Fenix5 had a review stating he PGA'd with kbinter.

As this came out during the game, kbinter attmitted to PGA'ing with Fenix5 but they weren't PGA'ing this game.

Later in the game, they defended each other and attempted to take out smaller players together in order to score higher flags.

At this point Kehoe enter the table, chatted a bit, and when it was pointed out that kbinter and Fenix5 were probably PGA'ing, Kehoe confirmed this and said it had happened multiple times before.

Not sure if this warrents any action, but it seems very clear to me (and several other players) that they had PGA'd before, were PGA'ing, and are likely to PGA in the future.
