TheDemelza, needs a rank change.
Also any idea on how we stop people from picking ranks that are to high for them.
Done. 
People will always pick false ranks by accident or on purpose. It’s a dynamic process and nothing we’re too worried about. We will implement more and more measures over time on how to find ranks better and quicker for people.
Thank you kindly, I guess forcing all new accounts made to be forced set to 30k is not an option? High ranking players might not like that idea.
While it sounds intriguing to use a system like that (How KGS is using it, for example), it actually brings up a lot of other problems; which are equally hard to come by.
A perfect ranking system is close to impossible to create. 
We chose to do it in the current fashion, and will try to improve the system (and have been improving several times already) over time.
I also play more often against people with a false Rank. A solution could be, that new player have to absolve against a bot or a player something like a testgame. The points of the result and the self-classification of the player will reveal more about a rank.
