I say admit to it or else we have enough reasoning to go to COI. A COI would result in you not returning in any reasonable amount of time and your style is now known by a couple editors so any sockpuppetry would be easy to stamp out. If you are socking: Fess up, apologize, show an effort on other topics, stop pushing peoples buttons and screaming about bias and see WP:OFFER. Of course, I wouldn;t be shocked if PS is not the sockmaster but just a sock of another sock. Play by the rules and everything will be easier and less drama. Or continue to be rude and be shunned. I have found being shunned kind of sucks but it is nice still being able to edit for not crossing certain lines.
