Lots of other people have tried this. Its more about the kind of people following you not how many. Once you are following to many you can’t keep up with your feed. While f4f might be a way to start. Long term it’s not the best tactic in the world. It just gets you people who are spamming follow and they are not going see the random blog you put out. There feed is moving as fast as Steemit.

I get a lots of follows and then unfollows a day later who go around spamming and then unfollowing people who don’t follow back. There follow in the first place is not worth anything to me because it is not genuine.
