FAQ > Twitter Account Management Service

The "auto-follow-back bot" used to follow-back all accounts that I hadn't follow-backed. But recently, the "auto-follow-back bot" doesn't follow-back all of them. Why? Any algorithm?

Surely, we know that our "auto-follow-back bot" hasn't follow-backed all of them. But our "auto-follow-back bot" has follow-backed all of the not-yet-follow-backed accounts.

So, we think that twitter doesn't accept any follow-back-requests that our "auto-follow-back bot" does. We infer from some cases that twitter doesn't accept the request for "suspend accounts", "accounts which similar to account that you blocked".
