how dow the alias 'medsomedso' who has an 0-1 record in chess 960 get a 2599 rating?
 
I've noticed a large number of 0-x players in chess 960 all up over 2000 ratings and most start games with me and then never play. luckily my games result in being aborted because they never move, but I'm guessing they're using that somehow to get inflated ratings.

If they have only played one Chess960 game then they are still in their provisional rating period. Their rating is still being established and not yet indicative of their actual skill level. You can go to the "Help & Info" tag above and then "Player Ratings" for exact details on the Provisional ratings.

I'm not very good at Chess960, but playing AgentSmith, 'who' has an extremely high rating, has made my rating go up, even though I lose every game against 'him'. I think this is part of a rating bug, where players sometimes gain points for losing.

I understand the provisional system at this site, but does an 0-1 record justify a 2599p rating?

I'd like to clarify that I don't really care about the absolut number of their rating as I know it will correct over time. The issue is that I like to add a lower rating bound when offering games to filter out exceptionally weak players and when people with no wins at all are rated that high I end up playing a lot of players that shouldn't be in that range.
