Hillside SPCA review: Privacy concern

My husband and I recently adopted an adorable pitbull there. We went to see the dog and all that. Well my husband signed the adoption papers and like any spca you have to agree to random visits without notice that's fine with me. Well I wasn't there to pick the dog up my husband was and he wrote all his info down and me as an emergency contact. Well all the people that I didn't meet there the one day i went are looking me up on facebook and used the info my husband gave them to find me and it creeps me out . None of them sent him a request. Just me . And none of them knew my name it was only on paper so what does that say. You can just use someone's info for anything ?
