A few weeks ago I bought a few proxies around 5 or so completely private and I made Reddit accounts with them. I tested them to see what kind of affects they would have on low population sub reddits. It was very odd because I would post something on a 100 subscriber sub-reddit and then I would try upvoting my post with the proxies. The outcome was very odd, I was getting my upvotes, but I was also getting downvotes at the same time. But I know that people weren't actually down voting me because the subreddit had like 50 users. I would refresh my page and I would constantly see the numbers of the downvotes/upvotes and score change. They where all changing rapidly, too fast for such a small sub-reddit.
