Using the service is generally an acceptance and agreement to the terms of service. A similar analogy is that I may not want to read my credit card bill, that doesn't eliminate the responsibility I have to pay it. Or, I may not want to read my visa card notice they send informing of a change in the APR or other conditions for service. however, my continued use of the card is the standard way one accepts new or changed TOS. Maintaining ignorance doesn't excuse the actions.
