Hello , you know that Trackbase isnt related to splatterladder.com if you had your name registered there it doesnt mean it was registered on TB. ( just for info )
Sometimes that problem happens , some ppl steal/reserve random names with a certain rating and ask for a transfer.In general we take a look where the guy is playing we check ping etc to see if its similar but unfortunately there is not much we can do to be 100% sure that the name belong to the guy.

Well , if you want to recover your rating , you have to PM Paul, explain him what happened ( put that thread Url ) and you should get your rating back. Try to catch him on xfire to get it back quickly.
There should be some change on the next TB update to warn ppl who are stealing names , in case they continue they will not be able to request any transfer
