The developer, Guacaplushy#0001 decided to make RandomBot for fun. I already knew Python, so I googled how to make a bot. Now we are here, with it in more than 40 servers.
More about RandomBot: It was a useless app I had in the Developer Portal, and I already knew Python. A while went by and then I just thought it would be a fun idea to make a bot. So I googled how and got to work. I scripted up a couple commands and tested them, they worked. And then I started to get the hang of it, and now I've coded more than 15 commands into it.
