I shunned my brother... I did it partly because it was JW policy and partly because my mom said I had to. Same thing with an aunt of mine that was DF'ed...I wasn't even baptized and was just a little kid, but whenever we saw her my mom told me I wasn't allowed to speak to her because she "left Jehovah and is living a bad life". I don't even know my aunt and it saddens me that I was never given the chance to get to know her.
Shunning my brother was difficult. His wife was not a JW and so they used to come over with their kids so my parents could see their grandchildren. My dad was not a JW at the time, so he associated with my brother with no problem. Dad would make dinner, and my mom took seriously the scripture that says "not even eating with such a man", and she would take her plate into another room and make me follow suit. So we'd all be sitting there and mom and I would talk to the kids and my sister-in-law, but not my brother. If my brother came in and got in a conversation with his wife and my dad, my mom would leave the room and make me do the same. They actually asked me to come over and watch the baby every day while my sis-in-law was in school and my brother was working and I did...that was difficult because when my brother would come home, it would just be us...and virtual silence. And I think he was so angry about everything that he didn't bother talking. A few times he talked to me, but what he said was laced with venom because of the crap he was being put through, so I don't blame him for that.
He did eventually get reinstated, but I don't think he could have ever forgiven my mom for the lengths she went to in order to avoid him. He's inactive now, wants nothing to do with the JW's, and moved away. I talk to him every few months to make sure he's still alive, but it's clear that for the most part he just wants to be left alone.
