It was old Rooinek, so a bit strange.
Ha ha ...Taipansy ... Although that's ironic when it's coming out the mouth a dog treat
This is my list so far . . .
Mary-Anne = Taipansy (aka Taipan)
Truth_Fairy (aka The_Truth) = Stew (aka Stu)
Super = Obergruppenfuhrer Von Barlee (aka Barlee)
Apart from those three confirmed moles, I also have a few strong suspicions . . .
ArizonaMildtwat is either Unterscharfuhrer Hawkeye (aka Hawkeye, aka James Hunt, aka Falke Auge) or else he's an ex Kamp SS poster called Mats.
I'm pretty sure I know who Drivelling Avocado (aka Devils Advocate) is as well but I'm not as sure as I am with the others.
