well there is a guy i like at my school and lately i have been viewing his facebook profile a lot , i few days ago i removed him from my friends list and then went to view his profile and he had no privacy at all , i could see his photos his wall everything , today i still can but i noticed something weird and that is: there is a post on somebody else's wall and many people commented on it including him i can see his last comment but when i press view all comments , all of his comments disappear. it happened all day today. is it possible he knew i was constantly checking his profile and sort of blocked me??
guys are you sure cause several times i saw applications "check who views your profile" and stuff like that
