What beef?

Distressing mail:

A little man called Joe Craig with a short man complex is logging in
under my name and making stupid comments. As alot of people know me
under that nickname it is begining to piss me off. Plus he is
attaching links to his favourite farm sex sites. I am sure you can
understand my distress and as you don't want to be seen promoting
beastiality can you have this worm blocked or better yet have him
killed.

Thanks.

Dubsie.
