I see people accuse Trump-supporting tweeters of being Russian bots everyday. I assumed they were nut bars. How in heck do you determine a tweeter is a bot?
Simple. If you disagree with them, they are a bot.
I was involved once with a company that was getting hit by hundreds of people attacking it on the net. After an investigation we discovered that those hundreds of people were phony identities and it was all perpetrated by 3 ex-employees.
Another example is drug companies having some PR firm cruise the net and pretending to be regular citizens defending the over drugging of children. “Ritalin saved my child” and other such PR operations.
The net is vile. Believe nothing you cant prove.
