This is something I thought about too. Especially considering communities like /r/The_Donald and 4Chan's /pol/ have been observed creating parody Twitter profiles and the like with Russia based geo-tags. I am nearly positive the image linked by OP is an example of just that. This is not to say that Russia did not purchase Facebook ads, just that a geo-tag is very weak evidence of anything and using images like the above to make accusations makes for a pretty weak argument.

You can manually set your twitter location to whatever you want for any tweet, and the account mentioned above was a parody/troll account.

The idea that this is proof of Russian meddling in the election is laughable.
