Interacting with Other Users
When offering services or products, you should put forth some degree of rules and guidelines for its usage. If someone does not adhere to those rules, it generally results in abuse of your service. In your guidelines, you should cover all the areas of website usage you want to enforce or limit. This can include user communication, the consequences for not abiding by the website terms as well as user limitations.
Protecting Yourself and Your Ideas
You should advise users that their accounts are subject to termination if they involve themselves in any form of prohibited activity. This is also known as the Termination Clause. You have the right to ban users from using your service for having violated the terms and conditions of your website.
Finally, annotate in the terms that the owner of the website cannot be held responsible for any kind of error or flaw found in the content. This is to limit the owner’s liability helping to avoid potential lawsuits. Some website owners include this in their Disclaimer section. Such section is also found in the beginning of many books as to protect the writer or author from being held responsible for any error or omission.
