I'm a reasonable person of sound body and mind and very well socialised (I'm certain that I don't have a mental illness). I've been on the sub since there were 20k users, there are now 120k I've helped countless newbies and formed relationships with other long term users of the sub who also have a high reputation. I've made many high quality posts on bitcoin data analysis (and a few crappy memes along the way).
Something is definitely different in the past few months, and a lot of the other old timers would agree with me, the subject matter is not normal. I have loads of anecdotal "Wait a minute, that not the way things are meant to work" situations, where some comments are being downvoted and upvoted abnormally. Some comments are meant to only confuse you or deride the conversation and bring it off topic. Some threads are calling into question the Mods and their motives. Some comments on threads are pushing the traditional banking system benefits. There has been an influx of 0 day users who seem to speak on authority about financial instruments. These are not trolls. Some users will reply with what seems like a positive post and then flip completely 180 degrees by the end of their reply.
What I'm trying to say is that the human neural network pattern matching machine is incredibly good at finding inconsistencies, my alarm bells are ringing, there is some organisation at work in the sub.
I would like to start gathering data on the extend of this by comparing users account age, their topic of conversation and the techniques they use. I'll need some help from my trusted friends on /r/bitcoin and I'm still coming up with the process on the best way to collect information to prove or disprove my hypothesis.
