Look at Amazon. Fake accounts are hard, so hard to make that they sell in the $1000s. Then it's still incredibly hard to actually use that fake account because so many actions will get them suspended. That's not to say Amazon isn't rampant with scams because the profit incentives from a single account are so great. You can sell a couple hundred 2TB Thumb drives for $30 per day and it will take a month or longer to accumulate enough bad reviews to have the account shutdown. I don't think the profit motivations on Twitter will be similar enough.
