We’re looking into inconsistencies with follower/following numbers 3 years ago

The number of folks you follow or who are following you may have changed unexpectedly.

In some cases, small changes are expected as suspended accounts are being cleared from the system. However, there are also cases where people will follow a user and subsequently find themselves unfollowing minutes later.

We are digging into both of these problems.

Update: The relationships have not been lost; a replication lag has caused the problem. We will be putting things back into place.
