To be clear, it's a horrible post and I by no means think it should exist.
To be honest I don't think you should have rehosted the image here, linking the original submission should be good enough.
I've not heard anything good about exploding heads but this shouldn't be used as proof for what I can only assume is defederation.
Firstly, it's a brand new post, terrible stuff is going to get posted until moderation becomes better.
Secondly, ok it's posted to a hateful and shitty community called ihatetroons which also shouldn't exist, but we don't know how new that community is or if the exploding heads mods are going to get rid of it.
Finally, this post should be removed and a new discussion thread should be generated with the title, 'should we defederate from exploding heads'. That discussion should be used to gather evidence for defederation and request that mods here open a discussion with the exploding heads mod team to find out what their intentions are. Defederation can then be voted on in the weekly vote.
How do you use the brakes with globes on?
