I stopped tracking 'active users' and replaced it with 'accounts transacting'. The reason is that an 'active user' is hard to define. As you mentioned, an auto voter is actually not an active user. Someone who found a Hive page on Google and read a few articles here can be called an 'active user'. It's not possible for me to track these users, because they didn't interact with the blockchain.

It's my assumption that we have a lot of readers on hive.blog, hence I think the actual number of active users is much higher.
