it seems good to new bee but as being experienced I can say that it is one of the worst thing you do on steemit because on steemit your followers are your asset if you will try to gain followers with your content they will be more loyal to you. If you will exchange follower-ship its not going to help you any more.
2nd Reason: Because you will follow them back but in the consequences you are going to fill your time line with a shit content, the content you do not have concern about and hence you can not make good relations with the others steemias who falls in the same interest zone as you.
