It is the "support" that is the problem and require people. I mean think about it this way, if you are wondering something about roobet then they could have an answer ready, and if not then they could add it if its asked too many times, those are all fine. However, if you are having a "problem" then it will always be a support staff, that will not change at all. I believe that we are going to see support staff forever, that type of human interaction requirement for complaints will never be gone. I do not care how much technology improves, it will always be required to have at least few people to respond to other people to help them out.
Even the problems could be a situation where they could fix via a bot until certain point. If you are doing something like forgetting your password, almost every single website in the world has "forgot my password" button and it is automatically handles it, that is still your problem but it is automatically fixed.
So, there are some stuff that could automatically fixed even if you have a problem and not just a question. I also believe that unless your account gets frozen for going against the rules, you could honestly find the answer if the FAQ section is vast enough, would require tens of pages for something like that to be fully covered, but it is not impossible neither.
