I've used an iPhone app called Defriended for a while now, works like a charm. All it does is keeps a list of your Facebook friends and then reports on the changes - adds and deletes. It doesn't tell you if a person actually deleted you or if they deleted their account altogether, but it's easy enough to search for them and see if they still exist on Facebook.
Why does anyone add people who they don't even know? I see no point in getting, "1111!!11!11elevendy" friends.
So my point here is, you wouldn't have to worry about that if they were actually friends/people you really know.
I have requested a friend invite from people who I knew who they were but they didn't know me.. and I was curious to see what they look like now and what's up with them..Let me explain more
I requested a friend request from my nephew but he has not seen me since he was 4, I moved 3,000 miles away to California and his mother (my sister) and I did not keep in touch, but I changed a lot since he saw me, I was only a teen now I am an adult and had lip augmentation, my hair dyed lighter blonde and lost weight..I thought maybe he'd remember my name and remember I moved to California but originally from Connecticut..My first name and where I live and where I was from was all on my profile and I thought maybe he'd put it together, because he still knew of me even when he was a teen and now he is 25. So I requested an add from him so I could see all his pics and see what's up with him and he accepted my friends request and I didn't say anything to him, because I haven't been close to his mom, I haven't seen him for years but I was just curious to get into his profile to see his pics and what he is up to and then if he would had asked me if I was his aunt, I would had talked to him, a few days later he deleted me from his friends list..Not a word said..I don't know if he caught on who I was, but why delete me or he thought he didn't know me so he just deleted me but it's funny if he deleted me without realizing I'm his aunt...Now I don't know.
THEN when I had another Face book account I found my father's recent wife, my father never kept in touch with me growing up because my mom moved me to California and we lost touch. (yeah ****ked up family not close) anyway, His wife never met me and never knew me who has the facebook added me to her friends list after I requested an add, same last name as hers and the last name is not common, and she never said a word to me...I deactivated my other account because nobody talks to me on there or adds me like they do on Myspace, I have a lot of friends on Myspace..Anyways some of my Myspace friends said they were heading for Facebook so I made ANOTHER face book account, attempted to readd my father's wife and she rejected my request this time..I wonder if she even realized I'm her husbands daughter from his first marriage..The last name is not that common...
Then I saw some old high school people I have not seen since I was 14 when I had short hair, braces, was chubby with acne and I look like a totally different person and I doubt they will know who I am but they still have me in pending LOL
