Stay in context, genius, you know exactly what I mean. Not bot or algorithm can do anything about a review, left by a real customer, with a real acct and purchase history, so yes, it's "real". Not being truthful is another thing.
Yeah basically if you want free stuff, then you're incentivized to leave good reviews so that they are more likely to send you free stuff. Plus, there's a cognitive bias where you didn't pay for it so even if you would have been critical you're more likely to say something positive.
