It's absolutely not the same kind of behavior.

The one obvious 'shill' I ran into didn't seem interested in changing my view at all, they seemed way more interested in very superficially making it appear as if I was just wrong instead, switching in jumps from implying I was delusional to attacking my source to accusing me of cherry picking data to suit 'my' narrative and finally accusing me of being a Trump supporter. Is this proof? Of course not but it was also very unusual (and I've been around here a while, I've had plenty of political discussions with people fired up about their candidate) and definitely made me curious.

So I looked at their posting history, something I have never really bothered with before but am definitely doing now. I get that everyone uses reddit differently. I understand that it's possible for someone to set up their subreddits so that they only see /r/politics, /r/politicaldiscussion, /r/enoughsandersspam, etc. You know what's downright weird though?

Page, after page, after page, after page, of absolutely nothing but comments about Hillary Clinton, her Campaign, and attacks against other candidates. It all starts exactly 2 months ago. Hey I understand deleting old comments I do it myself. Only they aren't all deleted.. it's a 2 year old account and there's a comment from 2 years ago, and then 2 comments from 2 months ago in /r/chicago and /r/askscience... and then 11 pages of pro clinton comments, vigorously attacking people from any and all angles.

I look at your comment history and it's obvious you're a redditor, who uses reddit and is having discussions about things you care about.

This other users comment history does not look authentic to me, it does not seem or feel natural to me, and now that I've started looking for this stuff it's not the only one I've seen with a pattern like this. I haven't found any Trump supporter or Bernie supporter histories that look like this at all.
