I've gotten this plenty:
I'm a busy guy so I use Tinder, OKC, POF etc alot.
TONS of girls put their IG's on tinder, like others have said, their thirst is real for followers on social media.
FIRST: Use this to your advantage, see if they're SIF's, legit, or anything that can help you text game them. The more you know about a girl the better of an advantage you have to get her number.
My first questions are:
How are you asking for the girls numbers ?
Do you keep it light and funny before ?
Do you use any of the lines in the Tinder thread to get the number?
How long before you ask for their number ?
How do you open them, or do they open you?
When they ask for your IG or FB:
-Tell them truth "Yeah, I've got a facebook but it's for my private business only" if they ask for it say "I don't add anyone I don't know in real life" or "hey how do I know you aren't some 6'4' 500 LB dude named bubba, let's see some proof !"
-Always turn these requests on them, always make them have to prove things.
-Create an IG, post cool things but only a few pics then say "yeah I have one but I barely have time to use it" or something of that nature, flip it on her.
-@Atlantic is right, get a snapchat, you can text & great for nudes & whatsapp as well.
Personally I refuse to add girls on FB, but my IG has 1000+ followers and I'm doing fun shit when I'm not working, so inadvertently I've cultivated my IG to show SMV (with a bunch of girls, out having fun, extremely social, and adventurous).
I also do a burn the ships approach, I either get her number by text game I've employed via the Tinder thread OR I move on to the next match (plenty of them out there).
I will not give into a girls demands or her not giving me her number.
Some great lines I've used to get numbers are as follows:
Kaotic -"So i've got an important questions before I get your number"
Girl - "Oh yeah what's that ?"
Kaotic - "What's your number?"
Kaotic - "2 miles away ? Are you stalking me !? I'm surprised you aren't texting me outside my bushes!"
-follow this train of thought to get her number-
Kaotic - "I've got 3 important questions for you"
Girl - "Hahah okay what ?"
Kaotic - "So 1. Funny/Interest Question 2. Funny/Interest Question"
Girl: "Answer 1, Answer 2, wait you didn't tell me Question 3"
Kaotic - "Answer 3 is your number"
-Challenge the girl with something to prove her self worth-
Kaotic -"Look I'll be honest you're cute but what makes you different from other girls OR (other tinder girls)"
Girl - "I'm blah blah blah"
Kaotic - "We'll see about that when we hangout, number?"
Kaotic: "You know I'd get your number but how do I know you aren't some 6'4' 500 LB dude named bubba, let's see some proof !"
-Last ditch effort-
Kaotic: "For all I know you could be some 6'4' 500 LB dude named bubba, tell you what send me a pic with you flipping me off and your tongue out and I'll believe you! -your number-"
^^^You'd be surprised that it actually works, girls love taking selfies.
ALWAYS PUSH FOR THE NUMBER CLOSE
If you don't get it, don't sweat it, try restarting it later. If not, no big deal plenty of girls online and in real life around you.
Don't ever let getting a number get to you.
EDIT:
Fortis, just read your clarification.
Since you've already number closed them online and have their numbers, you can use some of the things I talked about above.
-SnapChat for selfies and nudes (she'll forget all about IG and FB)
-Tell her your FB is ONLY for work people OR maybe if she's lucky she'll get a friend request from you.
-You'll explain in person (it's complicated) why you don't have a FB.
-Send her pics or memes or funny pics to distract her before the meet.
-Change the subject immediately.
-Flip the scripts "are you gonna creep on me !?
" or "Do I need to file a restraining order already hahah"
