I sometimes like to do a little hacking on KA with POST requests, but I know there isn’t a lot of info on such topics. So I think it would be cool if KA added courses that teach the inner workings of HTTPS requests, website code, etc., and it would also be nice to have sandboxed challenges where users can test out their skills. This does have some pros and cons: Pros: Students can get a start on learning white hat hacking, which many companies pay lots of money to such people for finding exploits. There will be many more people hacking and testing for vulnerabilities that they can report, helping KA improve its security faster. Cons: People will gain this knowledge and use it as a base to attempt maliciously hacking KA’s servers. People may start using disabled features through hacking, such as posting questions in their own programs or unvoting programs (both of which I know how to do). As a result of any malicious hacking, user data could be compromised. People who have Inspect blocked may not be able to follow along. These are some things to keep in mind, but I hope you’ll all take it into consideration! Keep on helping the community!
