Someone from bumble contacted me on facebook -how?

[DrinkingTooMuchPinot]

Good evening,
As the title says I have just been contacted on Facebook by someone who had seen my profile on bumble and obviously I didn't swipe right for them.
How on earth did they find me? I have not linked my Facebook on bumble, my Facebook account is set to private, I didn't even use my real name (the spelling of my name is slightly unusual and I used the more common way to spell it on bumble). They are commenting on my profile picture and are from the same city.

I've only used bumble for a week so a bit concerned now that someone was able to find and message me.

‘I have been contacted on Facebook by someone who had seen my profile on bumble and obviously I didn't swipe right for them.’

That is not diligence, it’s pushy and weird.

Even though your Facebook profile photo is different to the one on Bumble, is it still recognisably you? It's possible he searched for you on Facebook, tried different spellings of your name when he couldn't find you initially and then knew he'd found you when he saw your photo.

Might be best not to have a photo of yourself on your Facebook profile?

The bit that sticks out for me is that he could comment on your FB profile picture. you need to go into your settings on FB and click that only friends can comment on your photos.
It may also be useful to click the button that says you don't want your FB profile to be searched via google .
I hope this helps

He could have searched your name on FB and it would have brought up not only exact matches on the name, but variations too. If he knows your rough location he could have narrowed down the 'matches'.

Although a different picture, would he be able to tell from the FB pic that it's likely the same person?

I would be like omg how did you manage to find me on here and then when he tells you block and delete him and then report his profile on fb and bumble if you can

I had this happen multiple times when I was using online dating apps. Completely baffling why men think if you've said no on there, you might say yes that them hunting you down on other social media.
I figured it was because you're definitely in their local area, so they just search your first name and look for someone they recognise, or reverse image search a photo of you. I never thought they sold data, but things may have changed!
Either way, bloody creepy.

Thanks for the repsonses.

To clarify, I never revealed my last name or even my first name (changed my first name slightly, like Sara instead of Sarah because the spelling of my name is unusual)on bumble, and never matched with this guy, in fact don't even remember seeing him there. I also listed my job title as 'senior professional', not the actual title, so a bit freaked out how he found me.
I have done my due diligence with people before as well, but ONLY when have agreed to go on a date with them, never on anyone just based on their profile when they haven't even matched with me.
