What do you mean by registrar? What do you mean removed file hosting site for another website and how would they give you a warning for this one? If I'm correct, I can recall they supposedly wanted to make Gurochan's permanent home here and say they would be handling legal matters (as par statements on main page).

What will you redirect the domain to? Are there more that just 2 factors of sabotage? Most importantly how can I contact you privately for certain manners?

Last question, who is this person in relation to the site? A (or a few) disgrunted ex-partners/employees? Regular enemies? I read the statements but don't fully understand their importance/significance.

I would also explain the sabotage and give timestamps of when it happens/how quickly it gets handled to the registrar so they can maybe guard against it or understand.
