There are bots on both sides, but there is no proof that either Trump or Hillary's teams have bought likes. As anyone can buy likes for a retweet. For instance fans of Hillary (or Trump), or the opposite, enemies, such as followers of Trump or Trump campaign could buy likes/reweets for Hillary in hopes that someone would create a conspiracy that she's buying likes. Or vice versa, Hillary's team or followers could buy likes/followers for Trump to create a conspiracy for him.

So the fact is bots rewtweet tweets, but there according to this article at least 0 facts that anyone on Hillary's official team bought likes for the retweet.

what's more likely though?

Random fan buys thousands of retweets/likes, or campaign known for astroturfing (http://www.theatlantic.com/politics/archive/2016/05/correct-...) buys retweets/likes.

It's most likely that the bot is retweeting random or high profile tweets to establish account credibility, as happens with facebook like sellers.

Don't slip to the conspiracy that confirms your worldview so quickly without considering much more likely reasons.

On facebook, fake accounts will often like legitimate pages so their accounts do not get flagged when liking pages that paid to be liked. It's not inconceivable and probably likely that any highly-retweeted tweet will be again retweeted by bots to establish credibility for the bot account.

Additionally, the first 'truth' about this that the site provides is:

    1. Hillary Clinton’s social media team use bots for establishing 
    the record of retweets during race 2016 social media war.

Zero evidence is provided to support this claim. The existence of bots retweeting a massively publicized tweet is not evidence that the social media team of a specific candidate intentionally paid for followers.

This is a very poor submission coming from an account that has submitted this blog 3 out of their total 4 submissions.

It looks like the same strategy as used when rigging elections in South America: https://news.ycombinator.com/item?id=11397113 Whether this is ordered by the candidate's staff or not, there will be no way to trace the origins of the bot purchase.

One order follower bot retweeted one of my tweet for no reason. I think it is more how they advertise.

Why does anything that happens on Twitter matter to a national election for a president?

If it does matter, something is very wrong.
