That's right, you can see hundreds of projects with evil intentions doing that in the market, and it's not really difficult to spot such things if you have a little bit of experience. When a project tries to create a fake social media presence, they will first buy followers which will obviously be fake because you will barely see them interacting with their posts or tweets. However, if they also buy interactions from a website that sells such services, it will still be clear.

When a project has bought followers and post interactions, the comments that the fake accounts will be making will give it all away because they won't be related to the project at all and we all can know how a real person writes and how a bot does the same thing, so that gives it all away if we check properly.
