Please help with an abusive user

I have this problem ... There is this user who keeps on creating profiles leaving rude comments to my questions and the deleting them. Then the next day it starts all over! I know its the same person because all of her answers to me have to do with the same thing! Errr it makes me mad that people are so immature. This user makes really rude comments to some people on here. And it is really hard to block this user due to the fact that they will just delete their profile and create a new one the next day!! Is there anything we can do about it?

lol, yes we can block their IP, but they need to have an active account for us to be able to do that. Do you know what they're called at the moment?

Yes, you can tell an advisor. Or block them.

yesterday they went by igor, and today they started off as dudda ... but this is really weird because now where the comment was is another users profile and name ... I just want them to leave me alone

just let me know whenever the person comes back, we'll get them yet!

a sad person very sad I hope they rot
