This emoji bot simply take into advantage the fact bot can use animated emoji and can get emoji from all the server he is in.
So to get a full list of the current emoji you just need to type `$emoji list` or `$emoji help`, once you have the name you can 
type $emoji then the name of the emoji (no need to care about capitalization) and you can add a number between 1 and 9 to put 
more emoji. For instance you can try `$emoji blobrave 9` (which is the same as `$emoji BlobRave 9` btw).
What will happen next is that the bot will display your emoji and delete your command message to make it more streamline.

Disclaimer:
As this bot can be added on any server and there is no restrictions, you might see emoji you dont want if you type $emoji list or 
$emoji help , i recommend using it on mature server only then. I am not responsable for the use of the bot.

The code is freely available on github (its an awful piece of code but as it is so simple i dont see why i should bother with making
it scalable at all)
Its up 24/7 hosted free of charge for you.

It require the permission to manage message so it can delete the command the permission need to be set to 8192 then.
