> As far as the subreddit, I subscribe(d) to several quite different ones so that wouldn't explain why my comments in all of those would be downvoted. Your comment history across all subreddits is one click away. To give you an example of how quickly it can escalate, I once saw a comment that was completely incorrect, of the form "Wow, it's interesting that X is caused by Y!" I left a simple comment, "X is caused by Z, not Y." and left it at that. The original comment subsequently received a single down-vote, and not from me. Likely someone who saw their comment and saw that it was wrong. The original commenter replied to my comment, "Thanks for the reply, but it the down-vote was totally uncalled for." A few minutes later, before I could even respond, they deleted their comment and then every one of my 100+ comments were down-voted. Most of my comments prior to that had zero down-votes at all. That's just my anecdote, and it's still possible you were subjected to coordinated down-vote ring, but you said this was the result of an isolated incident of 1-2 small disagreements. It seems more plausible that you were just tagged by a vindictive Reddit user than something particularly sophisticated.
