I don't mean to sound like a total computer-ignorant moron here, but my family's having a little net-drama and I want to try and help them.
Basically, my brother got into a fight with a douche. Douche threw bottles at some of his friends, my brother called him names, douche threatened him with a baseball bat. Douche goes home, finds my brother on Facebook, "hacks" his account, gets his password and thereby passwords to his email and other personal BS. My brother changed his passwords and the douche was back into his account in a minute, they tell me. Genius that he is, my brother gets on my sister's Facebook account to chat with the douche and get him to stop... exposing her account to probable douchery.
My mom knows nothing of computers, and asked me for help. I know very little myself, and all I could tell them was to contact the Facebook administrators and alert them. Is there any way to prevent the douche from continuing to obtain my brother's passwords? Changing them doesn't do anything. He knows who this person is IRL, his name, etc. I read that what he's doing is against the law, but nothing can be done without physical evidence that the password was stolen (and I would love to know what the hell this physical evidence would be).
I think it would be delightful to go to the douche's house and pummel him, but that would only create further internetz vengeance, I'm sure. Past behavior shows that the douche is obviously unhinged.
My brother is a douche too. I'm asking you guys for advice only because this is yet another thing he's doing to make my Mom and sister's lives difficult.
