Limitation of Liability:
If you’re commercialising the service you have online, you’ll likely want to assert your ownership over the material on your site and be able to control how (or if) others can reproduce or utilise the work you have invested your time, effort, and money in creating.
Set User Standards:
Will you need to delete account access if a user isn’t paying a subscription? What if their online conduct requires you to remove their access to maintain the good reputation of your site? By establishing the authority to do so and publishing the method by which such decisions will be applicable you can avoid any disputes which may make it to court later on.
