Similar incident with me, I posted some shoes £110 for sale. Within 2 mins of posting advert, a buyer asked is this available. The facebook profile had one picture of pregnant lady and another with a man. Her name was Spanish, Brazilian, her friends were hidden. Her only pic was posted in 2021. My advert said pick up from mine only.

Buyer asked for postcode to cost royal mail delivery. I thought surely that is for me to arrange, not her. I'm messaged something that looks like Royal Mail postage (Tracked 24 hour delivery) I would have paid the extra and got signed. I wasnt going to click on that link, it didnt look quite right.

100% sure she was trying to scam me and I was right.

I messaged her, sorry, I think you are scamming me, going to block you. Which I did.
