Absolutely, without a doubt. Depends on the personalities of the elders. I knew an elder that was determined to catch a sister by constantly calling her, trying to visit, asking family about her. He was finally able to DF her when he found out she was pregnant and continued to ignore him.
Other elders in the same congregation were much more liberal/carring and didn't take much time to catch "wrongdoers". They moslt waited for you to come forward on your own after trying to contact you for awhile.
That other elder was a young self-righteous prick, imho. Also, I think he made it personal with her because she was interested him for some time but he would just play cat and mouse with her. I believe he is single to this day. Probably a supressed gay guy. Funny but sad.
