Seriously?
Would you take offence at being described as a muppet? Would it bother you so much that you'd go to the trouble of reporting it? If you were a MN mod would you delete it?
This isn't really a TAAT before anyone gets their knickers in a twist but, really, on a site where MNetters regularly call other women names I would never use such as
C*nts
Bitches
Wank stains
Old bags/hags
To name but a few, is muppet really a delectable offense? And who in the name of Justine actually reports this stuff...
