I used to have a base here last year on the beach with the large dino skeleton, I think around October time. Came back to the game around a week ago and checked out Viking Bay to see that he had expanded his base over what had been my area but he's just plopped down gateways and foundations to claim the area, no real buildings of use and the odd dino plopped down here and there. Back when i used to play it seemed that he'd log-in to Ragnarok to reset his timers and top up the food on his tames before disappearing again. From what I saw back then and now his main area was the large cave there and the area outside of it while the rest of the base was unused. Also I think the picture Roofpigeon posted with the mspaint outlying the claimed area actually shows a smaller area claimed than Nep has there, upper left area is expanded out further I believe claiming an even larger area.
