Protecting tweets and removing unknown followers

I have decided to protect the tweets of my personal Twitter account to limit the amount of followers completely unrelated to my interests. I have also removed many followers (not blocked, just forced to unfollow my account by blocking and then unblocking). I had over 500 followers, and I reduced the number to 165. If you believe I removed you by mistake, feel free to follow me again, and I will be asked to approve your requests.
