Be careful when taking pictures with your phone camera too. Phones have a GPS tracker and a stalker can get your location from the picture. If you want to post pics of your quilts I would use a regular digital camera not one on your phone.
I too, have had scary situations. I was stalked by an ex fiance long before it became a crime. And another time my husband received a call from someone threatening me if he didn't pay him. What the caller didn't know was my DH is a former police officer. He found out the guy was calling from a prison. How he got our phone number I'll never know. There's too much info out on the net. It pays to be careful.
