A Minecraft community with autistic kids and retarded staff that don’t do their job right. Mca is getting taken over by dramatic seeds pro users. 300K+ members but only about 100 members online constantly which isn’t that bad but could be better. Buggy wastes his lif everyday being on this app. Sugarlicous wasted so much of her life that she made it to lvl 16 in less than a year. She doesn’t know what outside is. Most of the members there don’t even play Minecraft anymore. The chats aren’t even related to Minecraft most of the time. Only posts and shy disables post that are related to Minecraft sometimes. The vc’s are insane and I don’t know why we wasted our life on this app. It’s like an addiction.
Little boy: Have you heard of this app called mca?
Older brother: Oh, that app about Minecraft? You should leave it because it’s a piece of shit and I don’t want to see you on it everyday.

(400 days later)

Younger brother: I hit lvl 16! This will be my new hobby! :0
Older brother: New hobby? You’ve been on that app ever since you got it.
