Rofl, I definitely share some of the sentiments you have regarding crypto is a scammers paradise. That is pretty much due to ICO's imho. What you might want to do, if you do use this in production servers, and I am sure the keybase team will add the option not to use it, it is open source. So you can easily simply remove that, I know that creates a bit of work and will therefore make it harder. I am just saying if this is being used in something that you find as useful, than the extra effort is definitely worth it. There simply isn't a tool like Keybase out there anyway. They literally solved the WOT issues related to PGP, and now they are adding some extra features which can potentially lead to other use cases. There are always upsides and downsides to anything. Imho, the upsides here might be justified, given the unique position that keybase is in.
