That's an interesting thought. Which "UserID" would you like people to use - or are you really talking about your forum Username(s), and which of those would you prefer we use?
I, for one, have no intention whatsoever of "pretending" to be talking with different people if I exchange posts with one of your puppets - I'm still interacting with you irrespective of who you choose to call yourself in a given context.
Maybe it would be less confusing for everyone if I just went back to referring to you with the username you used on these forums for over 2,000 posts, over a period of several years, or if I just hyphenated all your usernames into a single "mega-persona".
It seems pretty obvious to me that if you don't want people to refer to you in a manner that lumps all your puppets into a single "entity", for convenience of reference and history, you could just pick a username and use it.
Since you don't want to do that, you can hardly blame anyone for "addressing" you as any and/or all of the usernames you employ here or even a completely different "catch-all", like "Bob".
