It's a little weird that you're being so vehement towards your friend/colleague's account and that they haven't written a single word of their own to defend themselves.
so they wont be able to write - he has a blocked account - he cannot write anything!
This is not entirely true. Your friend has the right to create an appeal account. But with this account, he can only write in the META section.
It seems that neither you nor your friend has read all the rules of this forum. Sometimes ignorance of the rules can play against you.
