Then, Rob Mitchell joined under the Fake Name of "muskraattt"


Didn't hide who I was. It was not a fake or anonymous.

So, I banned that user name and then he joined under a slightly
different name:
"muskraatt" muskraatt @ yahoo.com

Didn't hide who I was. It was not a fake or anonymous

did you imagine that nobody would follow the links?

you did hide who you were, and you were anonymous you picked a handle
(muskraatt) that isn't your name, and you referred to yourself as `he'
rather than `i'

why deny it? it is a minor `crime' and slippery sloan deserves all the
unwanted posts you can manage to get into his group, after him sending
so many unwanted posts to this board and all


-- the real anonymous fake

When I read this I thought the poster was Sam using one of his socks.
I apologize for my wrong thought. It took a spoof DMCA complaint to
giganews
but I now have the results of the decode tool that they make available to
newsmasters investigating alleged copyright complaints :-)

Unless my calculator is busted, that 9948053 is verizon.

BL's rattled by Brock and so has switched to posting his libels
anonymously.
When he was posting hot sauce libels against PT anonymously using the name
"Hal" and posting via pronews BL showed his capabilities. So
now he has switched to giganews after he was outed as .

Here's the headers from BL's latest offering:

Do the math yourself. "the real anonymous fake" = BL. Or maybe someone who
happens to use BL's computer or internet connection.
