The typical human guy with a question mark finds out that a mysterious user on MyStable posting embarrasing secrets like bread fresh out of the oven.

This wouldn't bother him if it weren't for the fact that said user (or users behind the profile) are using his name to carry out such insolence. And Anon is not going to tolerate that!... also he doesn't see any logic for the Canterlot High students to accuse Sunset Shimmer of it.

As long as Vinyl and Derpy are left out of it, as I feel they would not turn on Sunset given this Anon-a-Miss concept takes place after Rainbow Rocks plus they do seem like 2 of the school's sweetest and kindest students, then perhaps that is an interesting idea.

A part of me find this kind of funny. Only wanting to step in because they’re using his name.
