this is not really SE but didn't know where to put it 🙂
Step 1
Create a Twitter account or login with your exist account.
Step 2
Go to an active twitter page.
Step 3
Click on one of the tweets and
click on the retweets.
Step 4
Start following each retweeter and repeat the steps.
Step 5
Now wait 1 to 2 hours to get
follow-backs or wait like one/two days to get them.
TIPS
Don’t follow 1,000 a day, it can get your account
suspended in no time!
Don’t unfollow them directly after they follow-
back, unfollow them after a week
Don’t reach 2,000 followers in 3/4 days
and not in 2 days.
All those followers are ACTIVE followers and are retweeters!
With this method you can get 2,000 active followers if you do it good.
