Glad you posted this - its the epitome of malicious compliance! And a fantastic form of protest too. With Reddit admins threatening to demote mods unless they re-open subreddits, this move takes away that ammo. Additionally, after the initial boost in activity due to novelty, the sub will get stale quickly and users will think of migrating to other platforms like lemmy or kbin. I'm all for it!
Edit: This is what I'm talking about. Here is one of those Reddit refugees now!
