I used to get a "fake" friend request a week on average with FB. Someone told me to hide my friends list entirely, meaning that I even my own friends can't see who I am friends with. As soon as I did that, I think I have gotten one or two fake ones in the last year. My only guess is that my friends' accounts are getting hacked and the hackers are just networking through their friends list and friend of friends lists and adding people along the way. As for IG, the amount of spam accounts is almost unbearable. To me it is next to Twitter with the number of accounts. IG I average about 3-4 spam (porn or sell me followers) accounts per day. With Twitter it seems to come in chunks. I'll go a few weeks without any and then one day I will get 50-60 follower notices from obvious spam accounts. With both it makes the user experience unpleasant.
