Did anyone notice? Did the other site get your name and number? If not, just put a new one on and act like nothing ever happened. If anything comes out of your unthoughtful linking activities, just point to someone else. Can they prove it?

If you get caught linking to the oompa loompa dating service with your nofollow off, check your rankings and file a reinclusion request when necessary. Admit to your evil ways and it will surely be forgiven. Maybe. Sooner or later.
