Every other day, I get a Twitter alert on my phone that a bunch of people on Twitter are suddenly following some new account. I click on that account and, lo, it's someone I'm probably interested in following. How did that happen? Because a bunch of people were interested in what that person had to say; I didn't even need to know I was interested because Twitter went out of its way to make that happen.
If you want people to listen to you, join conversations. Or, better yet, build or write things and then link to them in conversations. People will follow you if you add value. I don't believe anyone that anyone cares about looks at Twitter profiles to count followers before making that decision.
Also, bot-favoriting things is extremely annoying. Don't.
