Years ago I was working at a multinational consultancy, and then they suddenly decided to block most of the internet except for a whitelist. We quickly figured out that the whitelist worked with keywords, and since we were programming in java, java was one of the keywords, so if a url was banned, we could access it by adding ?param=java. As twenty something year old developers, we said, challenge accepted, and we built a GreaseMonkey or TamperMonkey script that when it couldn't load a page it would reload with the param added, and rewrite all the links and img tags to also add the param. Soon after that the system admin guys gave us a proxy config to bypass the whole ban, but it was fun to do it anyway.

I had a very similar situation. For some reason using the python requests library didn't trigger the company filtering, so one afternoon I built a little proxy. Handy when something something random was blocked.
