Well you first hasve to know if you qualify for a badge, the most common badges can be found here [https://derpibooru.org/forums/meta/topics/badges-and-stuff](/forums/meta/topics/badges-and-stuff)
If you qualify for one or more badges, you should say it here, specifying what badges do you qualify for, then a mod will see if it's true and he/she will grant you your badge, here's an example of how I got the `perfect plot provider badge`
