I should be very cautious about that you do not know where this info is transferred to.
the site maybe offline for a long time because the domain is no good or flagged by the SE’s and content is put on another. Maybe the owner has not had the time yet to do the changes.
I would add your email address on each page of the site you will use for your purpose, so if the owner sees his text being copied he can contact you asap.
