Per the Terms of Use for FANDOM, "you agree to . . . be fully responsible for all use of your account and for any actions that take place using your account." You further agree "to notify the company immediately in case of any unauthorized use of your account."

That first part applies but carries no punishment for you on this wiki. The second part, though&mdash;well, I cannot influence you either way, although I could tell you the correct thing to do. You can choose to notify Wikia that your sister used your account, or you can choose not to.
