For Twitter Active Followers, we use the “follow first method” (refer to this link), wherein we login to your Twitter account and manually follow people who are likely to follow you back. This approach is more effective in getting “real” followers.
Please expect a decrease in followers after since we don’t have any control over your followers but we will do our best maintain your target followers after. Maintaining and increasing Real Followers on Twitter is also up to the user on how to maintain a constant engagement to his/her followers
