There's no point in asking Facebook to delete your data. They will say that they have done so but in reality they will always keep a backup of ALL your information and activity for various uses. The only thing you can do is to delete your Facebook account and start a new one on which you won't give out any detailed personal information (you could put fake information for the most part) so that individuals who might wish to dox you would not be able to get hold of your info.
