What are you talking about? We try to set up a community where people can collaborate quite effectively, and when we encounter adversity we try to solve all problems that arise. If we add a little energy by helping people for free, then they can add value by helping each other and by allowing others to learn by reading their threads of collaboration. A lot of people benefit by participating here, and it is a "pure" kind of service because it is all about people contributing to one another's process.
If you do not read the TOS, you won't be able to proceed in a way that serves your interests. IF you do read the TOS but change your mind about your willingness to participate in the way that others do, then you can pay a fee to offset the time you cost us. But it's not as though we have hidden fees or something like that, and it's not as though we are getting rich by doing this.
