Note from a blog tour company says WordPress thinks some blog tour posts are spam. Well, when you say that tour hosts must post certain things, and give hosts stuff to copy and paste, and especially release day blitzes with no original content... What do you expect?
This is on you, blog tour companies. Lay off the "must include" bz, and maybe WordPress won't think tour posts are spam. ("Must include" = stuff like blog tour banner, contest, author photo. i.e. Stuff I'd leave out so hosts can personalise their post.)
