Dumb question friend requests

I only have my phone no pc

1 i get a lot of friend request on my Facebook but I don't know awayto see if these are ligit people .

2.Is the a way to find verified people on Facebook

3.i message people and get no response that's friend or request .is there a way to mass message people who send you friend request.Is there a way to tell if there real?

What's the best way to engage cause I'm not a great topic starter?

Ty for your time

If the account has a profile picture of a beautiful girl with 100 friends that are all guys you can bet the account is "legit".

Well the problem with that the ones with girls all have links to just dating sites,porn sites

I mean I have literally over378 request
And most are like I said above I literally haven't added anyone

Most accounts are from Europe Africa

Why will a real person with job and busy life send friend requests to random people ? Ignore those requests.
