I'm not sure if this helps or not, but reddit has algorithms in place to help remove votes created by bots. As a part of this algorithm, accounts without a clear history of contributions will have their upvotes counted as downvotes in some cases. This is why you see SA goons on the bitcoin reddit posting nonsense all the time (it's to help bring their karma up so that they can mass downvote better).
This may or may not have been the case here.
Leave how you came as you've said. Your input is shit scammer.
Do you know who helped design the security features in the checks and money you use?
Scammers! If it's just my input that's not welcome in the thread and not another person with this tag, then I'll gladly stop posting if the OP wishes me too. Thank you for reminding me to be humble about my past mistakes. It will take some time to live down I know.
Actually, reddit has a number of systems in place.
Vote normalization - voting is heavily normalized so top posts get around 2,000 to 3,000 upvotes. In reality, those posts actually can have 15,000 or more score (upvotes - downvotes), it is just that reddit admins keep the scores low for 3 reasons:
1) Less numbers are easier to compare
2) Keeping people thinking reddit is an exclusive club when it's the one of top 100 sites.
3) Allowing comparison of "topness" over time - otherwise, top posts would pretty much be composed of all recent posts, since there are more and more users (& upvotes)
This can be observed with posts before normalization (for example, "Test post please ignore" which was before normalization was put into place), and the normalization engine only works after the first hour is up (and the score is no longer hidden on the left). Steve Jobs' death had a score of 9,000 before the 1 hour mark, to which it was promptly normalized.
On r/TheoryOfReddit, there's being analysis of top submission's score, and it sharply went to ~2400 in a month and has being there ever since (give or take a few hundred).
Spam vote detectionObviously a lot of factors goes into this, and it's hard to reverse engineer. But "accounts without a clear history of contributions" will not have their upvotes counted as downvotes. That is another behavior, it happens when you vote a series of times rapidly without browsing new pages. Voting up will counter it with an automatic downvote (1 - 1 = 0), voting down will counter it with an automatic upvote (-1 + 1 = 0). This is mistakenly taken as "if you downvote on profile pages, it doesn't count" because it is not just profile pages that trigger that.
Buying Reddit Upvotes/DownvotesYes, there are bots that do this. Yes, they are still around. Yes, you pay money for them.
The example in this trend fits in a lot of the signs of paid for downvotes.
