The number of views it has and the channels they are following is in no way a definitive indicator of activity.
There are hundreds of thousands of active users who don’t stream so there’s very little reason for anyone to go to their channel and so have little or no views. There are many users who just ‘browse’ Twitch, or go direct to their favourite streamers so following channels isn’t important to them.
The user may also be using their Twitch account as a login for a site, or have their Twitch account connected to games they play, or any other of the many completely valid ways for them to use their Twitch account. Don’t assume it is “squatting” as there isn’t sufficient information to know how they use their account.
If an account is still functional, it is best to assume it is still active and wont be recycled.
