Is it still possible to earn a lot here in Steemit without Bots?

Hi Steemit I'm new to the community. I just posted my "Introduce yourself" post yesterday. I've read few articles here that there are some bots that upvotes for you automatically and I think its called "Minnowbooster". I don't know if it can automatically post a comment or an actual post. Is that a common thing here? Is Steemit okay with it?

Are there consequences in using "MinnowBooster"? I initially don't want to use it but now I'm thinking of using it. What are your thoughts?
