"Lurker member" is fairly self-explanatory, but what's a "mythical member" or a "folklore member"? I was hoping to get an explanation if I clicked on them or something but nothing came up.
They're member tiers based on how long the account has existed and how many posts the user has made. A folklore member is an account that has existed for at least a year, and a mythical member is an account that has created at least 10,000 posts and has existed for at least a year. You can find a more in-depth explanation here in Diana's recent announcement.
