All of those accounts were created with a specific purpose in mind.

/r/ModsAreKillingReddit was the original detection bot, I renamed it at the request of the admins to /u/ModerationLog so that it could keep sending PMs to users to notify them about removals.

But eventually the admins grew tired of that level of transparency

So I started up /r/POLITIC with /u/PoliticBot because I wanted the sub to be an eventual replacement for /r/politics (which I have been banned for largely due to false accusations of numbered alts)

I've never been shadowbanned on any account but PoliticBot before this, and that was for PI. It's been the most prolific poster on the site since it has been running. They only called it spamming when it disagreed with the administration in ways they didn't understand. Which I'll admit baiting but even though I begged for it there was no just cause to do so. Reddit is just arbitrary rule of men like any other government.

Regarding /u/ObamaCares yes I created that identity to separate from an identity that people like you have constantly attempted to soil for disagreeing with your flawed ideology.
