Doesn't that sound similar to hacking the system? We are using a website called hacker news. Not only was collaboration on homework encouraged, but the class actually had its own discussion forum for people to use. However, everyone disliked the forum because it was cumbersome and slow. So I built my own. At the end of the semester I had many people thank me for the website and asked to have it expanded to cover more classes. Using this forum I personally helped many students understand concepts and taught concepts that the professors couldn't teach properly. There were a few subjects I didn't understand and other students stepped in to help. You were not in my class and did not use this forum so I don't think you should rush to judgement about what was/wasn't cheating.
By definition, hackers do things that push boundaries. There will always be disagreement but you don't have to downvote just because you disagree. Voice your opinion, certainly, but please be careful with those downvotes.
