What's in a name?

I have been contacted by the Grillo family about the use of their name on responses to my blog. It seems someone is posing as their family member when posting here. They are concerned that people who do not know that's the case will believe a member of their family is making these comments. They feel it might reflect poorly on them because of that and politely asked me to do something about it. I agree. So the Dirty Grillo responder needs to change his Web name or I will have to delete the comments. 

When posting to this blog, I have usually allowed responders a lot of lattitude. No swearing. Don't say anything that could be libelous or malicious or crude. If someone is using a name that misrepresents who he or she is, then I feel that crosses the line, too. So figure out a different name and that will make us all happy.
