Handling 'intelligent spam'

[sharky93]

We have a limited resource of execution at our hand so need to save it from spam.
By 'intelligent spam' i mean robots using legitimate Python code generating images etc.
Introducing a CAPTCHA might be overdoing things since it would make the process more tiresome.

I think rate limiting requests based on IP addresses etc might just work out fine. Can surely start out with a simple system.

Any other ideas?

With the queue's in place, only a fixed number of containers are ever allowed to run at a time, so we're good for now. Might need an IP based filter in the future.
