Scientists create algorithm that ‘identifies future trolls from just five posts’
It is possible to tell comment trolls apart from other users simply from looking at the way they write, researchers have found.
Studying the comments on three sites – CNN, Breitbart and IGN – over an 18 month period, the researchers at Cornell and Stanford universities found that users who went on to be banned wrote differently to other users in the same comment thread, using fewer words indicative of positive emotion.
Future banned users also tended to write comments that were more difficult to read than typical users, the researchers found.4
“Studying the evolution of these users from the moment they join a community up to when they get banned, we find that not only do they write worse than other users over time, but they also become increasingly less tolerated by the community

Very interesting...

...would be more damaging than the number of words. At least one would hope so.
And regularly does. 
for years. Homophobic and anti-choice trolls have the most distinct pattern of any of them.
The exception to the trolls mentioned in the article are paid trolls, who are significantly more literate than the common dumbass RW trolls. Paid trolls are generally educated in the use of all propaganda devices, and use them frequently and effectively. They often use the same memes over and over for years, depending on the circumstance. Paid trolls are few, and are seldom banned because they are generally more intelligent than their total dumbass troll kin. They are dishonest by nature and profession, and can often be proven to be so, and their only concern regarding honesty is not easily getting caught at being dishonest. Their job is to convince you in any way possible, and for truth and honesty are expedient to the needs of their particular message. Half truths are critical to the effectiveness of their MO.
Professional trolls do not at all fit the pattern of the trolls mentioned in the article.
