Back to the Op.

Who claims to be a seller, yet doesn't understand handling charges.

A worry. Unless he has taken a leaf from Alex's book (whatever happened to Alex? Couldn't he handle not having the 'ignore' function?) and is trying to 'subtly' advertise.

Given he hasn't bought anything for 4 months that he's left feedback for.

I certainly wouldn't be drawing attention to my current feedback levels.
