Yes, she has the right, because moderator's have the right to ban people's IP address.
The only problem is that some IP addresses are shared. Sometimes when a vandal is blocked, legitimate users are prevented from logging on also. For the majority of blocks, only half to four hours are used, and it is impossible to permanently block an IP address. This is why I am forced to wait for an Admin or Global Mod.
That will not be helpful either because like I mentioned earlier Mods don't own banning rights. Issues like banning are strictly handled by the higher authorities only. This is the reason why sometimes "immediate action" cannot be taken as we have to wait for someone to log in first.
