Gamifying this kind of thing would be intriguing. I'm imagining some server that would work like spamnesty, i.e. you could easily let it handle your spam. But I'm also imagining the possibility of registering as a bot creator and plugging in your own algorithms. API-wise it would be super simple, much like creating a chatbot for Slack, but the logic could be as advanced as one would like. The server would then score the algorithms on established metrics such as "average number of responses" or what one might dream up. There would be leaderboards and stuff.

It would all work nicely until the spammers start creating their own bots to keep our bots busy. Bots would keep inane conversations going forever.

Then, I presume, Skynet.
