Legal side of it, Rukas needs proof. The problem is that:
The company just gave the domain back to someone else and I pressume that Rukas has been trying to get in touch if not already with this company, but as you can see nothing has yet resulted in it.
Rukas can take the guys who currently have control of hitemup to court, but is it worth it? Legal expenses, finding the people who hijacked the website, travel expenses, evidence. As of right now if you go to the website nothing harmful is being done to the name of himemup and to this site as well. I think Rukas made a wise decision in moving foward and forgetting about hitemup. As you can see this website is still thriving and Rukas career from what I see is booming.
