A few months ago I started a new twitter account with real, quality content and I used tweetadder to follow 30 or so people a day who were followers of a very similar (but much more popular) feed. I would only get a few new followers a day using this method but I did it for a while until I got to 300 followers (while doing the follow, wait one week unfollow routine). A few weeks ago I bought a Fiverr gig adding 500 twitter followers to my account. I knew they would all be fake but I wanted to see if people were more likely to follow an account with 800 followers than 300. After a few weeks I'm comfortable declaring the answer as 100% yes. Since I've done this my slow days have still been 12-15 followers (double my previous rate) and I'm well over 1,000. From now on I'll give all my new twitter accounts a bump like this. I know for a lot of you guys you do the mass follow by the 100s or 1000s but if you have an account you're trying to build and protect, this may give you a boost.
