微博互粉 is a Chrome add-on developed by mikertan that offers a convenient and automated solution for increasing your followers on Weibo. With this add-on, you can earn points by following other Weibo accounts, and these points will be deducted when someone follows you back. This add-on replaces the manual process of following other accounts on Weibo, allowing you to quickly grow your follower count.

To start using 微博互粉, all you need to do is log in and bind your Weibo account. The add-on uses a point-based system called "粉豆" (Fen Dou), where you can only be followed by others when you have a positive balance of Fen Dou. Each time you follow a Weibo account, you will gain one follower (assuming other users are using the add-on as well).

This add-on is fully automated, allowing you to automatically follow 20 Weibo accounts with just one click. The increase in followers happens automatically, without any additional actions required from you. Additionally, you can customize the conditions for following and gaining followers, which helps improve the accuracy of the process.
