Since 2016, there have been a lot of reports published and the effect has been to improve the methods used. Previously, they created a lot of web robots. Armies of bots engaged in massive information sharing. The bots were quickly deactivated by platforms like Facebook and Twitter.
They then came up with more sophisticated methods, to make the bots less easily detectable. For example, previously, bots that posted no photographs or profile information were easier to detect. Now, accounts are created in Twitter, LinkedIn, Facebook and Instagram and the accounts are then connected, to make it look like they really are a person.
Certainly, a lot of these bots can be banned. However, the more the methods are exposed, the more sophisticated they become.
Nonetheless, people are increasingly aware of the phenomenon. For example, when they notice that people on Instagram or comments on Facebook are often repeating the same things, they become a bit more critical.
Of course, that takes time. We become familiar with it and we learn, and the same goes for the platforms.
