Why is Facebook deleting my friends?

[A]

Friends have been getting deleted off my Facebook a lot recently. I had 326 earlier this week and now I had 322. I saw I had 322, re-added someone got deleted for no reason, was accepted and STILL had 322. I also found someone who's statuses I saw on my newsfeed probably two days ago is now on my people I should add list. Why does Facebook do this? i have no reason to believe people are deleting me. I haven't had the problem of it deleting close friends yet but it's still annoying... Is there anyway to contact Facebook about this problem?

facebook cant delete your friends, someone may hacked you

They might block you or people are deactivating their account

Facebook is deleting your friends either because:

→You have too many fake profiles
→Friends remove their accounts by deactivation or deletion

Good luck!
