Pretending to be someone you're not

There is a poster here who seems, if I understand them, to be claiming to be a lawyer, and one from a prestiguous law school at that. However, subsequent posts have cast considerable doubt upon that claim.

Is that sort of thing permitted?

Certainly when I was reading law at Oxford we would never have stood for such a thing.

This is weak tea.

SL, was the username “Ignatious J. Reilly” already taken?

For god’s sake, we’d better kill Skald the Rhymer straight away!

Yes, it is permissible to have considerable doubts casts upon your claims here.

I’m closing this OP.
Take it to the PIt. Lay out your case.

As one of my favorite sigs on this board says,

No one knows if you’re a dog on the internet, but everyone knows if you’re an ass.

Hope I got that right.
