You do not have an obligation to read the terms and conditions of the websites and software that you use. However, those terms and conditions/licenses may include language that you agree to them by using the website and/or software, in which case you have entered into a contract. Courts have upheld clickwrap agreements so staying ignorant of the terms of the contract you may have just entered into will not excuse you if you breach the agreement.
