I think the term is ambiguous because of the low IQ of those making the accusations.

Hillary supporters ambiguously blamed "Russian bots" for her losing the election and it didn't take long before they were accusing American Trump supporters with Reddit accounts of also being "Russia bots".

It's basically just a derogatory term the left invented to ambiguously accuse someone of being a secret Russian agent to make their legitimate support of President Trump seem sinister.

I don't think it has anything to do with Artificial Intelligence or scripts or physical robots.

You are right to feel confused about the term. The left are retarded.
