Custom statuses (Activity type 4)
Created by: uwx
Summary
This new undocumented/experimental activity type lets users apply a status without any prefix. During the experiment, it will only display in the percentile of guilds which are in the experiment. The remaining guilds will show no status at all.
Details
This was added at about the same time as Nitro Server Boosting (around May), so all the info on it got completely swallowed. I got bored of sifting through comments on Discord-Datamining so I don't have much information.
Notes
Be careful not to get yourself banned if you decide to implement sending this type of activity.
