Awesome thread. We were inspired to take a look at a couple aspects of Macedonia-related tweets.
There are 29556 tweets containing the word "Macedonia" from 14481 accounts in the last 10 days. Let's look at a random sample of 1000 accounts. . . 
Of these 1000 accounts, 98 (9.8%) appear to be bots based on 24/7 activity and/or posting 90% of their tweets via automation services. This percentage is roughly 3 times what we see on average.
This chart shows the media sources linked from the sample of accounts with Macedonia tweets (the sports site is likely a false positive.) The prominent appearance of RT/Russia Today is notable. Also, what's distressedvolatility(dot)com?
Oh, that's right. It's a spammy news aggregator with its very own botnet.
Finally, here's something odd. Three of the accounts noted by @josh_emerson as suspicious here are operating on a non-24 hour circadian rhythm (results in a diagonal tweet pattern in the chart).
We've also seen that timing pattern a few times before. . .
Thanks @ZellaQuixote for support/ongoing assistance with displays and methods.
