A year ago my family members facebook was hacked. It started with a fake facebook page and then her account was hacked and recently the hacker has been posting more and more. IS there anyway to find out if all these pages are linked to the same IP address? She has contacted facebook and yahoo without results.
Hers is the first page that has been hacked, the rest are the hackers pages
Unfortunately, there's no way to get a users IP via Facebook.
You'll probably need to contact authorities to see if they can help. Maybe an attorney if the local law enforcement doesn't want to help.
Usually weak passwords are what allow this to happen. I'd beef up my password on future accounts.
