Sue them for what? Someone got a hold of her login and password (which she admitted because she said there was also an activity notification on her youtube account that she just ignored), that isn’t on them.
This part of her story (quoted below) is just straight up wrong. Where does she think those hosts screwed up? Because they didn’t.
“Here’s why: the legal department at HostMonster informed me that in order for them to initiate a transfer dispute that would result in GoDaddy releasing the domain back to me, their “internal investigation” would have to turn up evidence that they had done something wrong in releasing the site. In other words, they would have to admit that they had screwed up…which would in turn open them up to a lawsuit.”
