about the terms and conditions of a service, what happens if i allready broke a rule?

like the terms of use for simply using your computer, if it turns out that i found out that i broke a rule months ago but never got caught for it, but now i know about the rule i broke at that time, and i find out that the terms of use says it was ground to immediatly terminate the agreement, and prevent me from using the computer, but aparently i never got caught which is why i am still able to use my pc months later since then, in such a situation breaching contracts and agreements without getting caught but never knowing that i am myself only to find out later that i did and that i apparently was not caught for so long what much I do?
