Guess what this does? It takes a 4Chan board and thread and dumps that shit to your hard drive. 
It does it via the API to, like it fucking should. Stop relying on third parties to save your "precious" threads. 
Requires Python 3 and requests. 

DON'T SPAM THIS SHIT more than once every 5 seconds, moot is watching you.
It's called 4Chain because moot's a cockslave to advertisers.
