How to securely confirm all friend requests in one fell swoop?

Question

Facebook

Guys, is there any way to confirm all those knocking on friends? I haven't been in for a long time, and there are over 500 people there.
And what are the tools to facilitate the management of all this stuff? Added a lot of incomprehensible Arabs. I would like to conveniently filter everyone, and through the FB webmord this is a terrible pain to do.
