I'm thinking that this is not as `black&white` as said.

There are accounts which actually are used by people/companies, they post authentic content but do some automated actions.

E.g. a company account which tweets authentic content for their field but on the other hand has automated retweets on certain hashtags in order to gain their authors as followers or to come up as related to other accounts in same field.

Also to mention that there are services such as IFTTT which actually can help you to automate such actions and make bot-like behavior.

I guess the same would apply to Instagram, Pinterest, Reddit, etc.
