It was the test community I made when communities were in beta.
It started as Coconut Rocks Community. Then I turned it into Crimsonclad Rocks on her live show.
Eventually I changed it to Themarkymark Fan Club and invited spammers who spammed and harassed me in retaliation.
In a nutshell it was initially for testing communities then made it into a joke.
I think I remember this. Maybe in a while, it will be time to do more stuff for communities. I have a few ideas to improve them, and I've seen a few get more interesting than just a tag and perhaps a discord.
