You can quickly spot them when they follow any sort of trendy thing that's going on in the Chatterbox at the moment; like making threads following a certain popular subject.
Some actually manage to gain a relatively popular status, but after a month of not posting everyone would forget them because they just aren't that interesting.
They're also considered 'Fail regs'.
Therefore they should NOT BE CONFUSED WITH A REAL CB REG.
