Recently Twitter removed the statement saying that this type of automation was permitted. They have also contacted us to inform us that automated followback is no longer allowed. Any followback that is made must be done by the user themselves, and not by an automated service.
Our primary goal at twiends is to provide a quality directory for social media, which allows you to grow your audience in an ethical and responsible way. We will only do this with the blessing of the social networks that we support, and we will observe their rules at all times. With this in mind, we have removed this feature.
Please see the following article for information on Twitter’s follow limits:
