Usage of markdown pastebin service instead of multiple messages

[CoasterFreakDE]

Multiple messages are horrific.

— Spam — Code Blocks splitting apart — Spam — Ugly — Bad to copy — Spam

As of this reasons, we need to paste larger responsed to a pastebin with markdown support like https://rentry.co/what

Here is an example: https://github.com/radude/rentry/blob/176a31c5c447815115be5582022695754a353ee4/rentry#L44
