Hi "agent from Malaysia".
It is well known that "Correct The Record" has been influencing the discussions and votes. In the beginning it was easy to identify them, because they just copy-pasted political statements.
They were very active during the primary elections. In some subreddits we had discussions whether there were any people at all on reddit that were in support of H. That was how popular Bernie was, and partially still is on reddit.
There also military level manipulations going on directly from military bases, and also manipulations by some Israeli agencies. Also the UK has active agencies, but they seem more subtle.
And then we have manipulations by companies that want to support their product (or favourite politician). There are even click-farms that you can pay to work for you, and companies specialized in manipulating social media (as Correct the Record).
And we have groups that work together to get upvotes and downvote unwanted posts. We usually call this "brigading", and while it is forbidden, this is also very common on reddit.
In 24 hours you can see the upvotes switch between soccer and football. Each nation has its own favourites and opinions. And I think that this is a good thing. We as different nations learn to communicate with each other.
Compared to all the manipulating going on, the manipulations of "Russian bots" is not much. And as far I have seen the influence, it is really overhyped. Frankly, if you really want to destabilize the US, you can do that by letting the internal political corruption bring it to the ground.
By communicating on the other hand, besides all bots and trolls, we can learn to see problems and solutions of our and other nations. See many different sides of problems and politics. This can be beneficial to all nations.
(Even Malaysia ;-)
