Twitter question. *DECKS* and BUYING FOLLOWERS*

My question here is

I am constantly Following people using (FOLLOWLIKER) is that okay?

also I am in a “DECK” group so basically its a group of bigger accounts that all have over 200k i believe and they just retweet my tweets.. which is great I’m getting a lot of engagement but I’m getting charged 3.00$ a day to do this.. am i wasting my money?
