Generally I use it to try and waste as much of Open AI and Microsoft's money as I possibly can. I try and get it to use the absolute maximum number of tokens as I possibly can for free doing pointless tasks, I use the image generation to produce the weirdest art I can without triggering the censorship and when I'm bored I just tell it as many lies as possible and make it treat them as truth.

I don't know if this is feeding into the training data or not but I hope that it is.
