[Closed] Can I stick summat on ebay but stop an individual numpty bidding/buying it?

Have bought sold/loads of stuff on ebay without much hassle but only because I tend to have collection only. It saves 'not as described/broken/missing' issues even if it narrows the field of available bidders.

Anyways - i stuck a bike frame on before xmas and ended up answering a lot of numpty questions from a guy a few hundred miles away. The mither got that bad that I pulled the listing (also coincided with major health problems in the family so didn't want the hassle). My spider senses were tingling with the questions he was asking - it just smelt of 'not as described I want a partial refund' setup even though the frame is new/unused.

Relisted this Saturday with clear details on collection only and with my town/location in the description.
Numpty #1 fires off a question first thing Sunday morning = whereabouts in the country are you (same place as last time we had this discussion!), before I reply he's hit buy it now and paid.
Cue long discussion about it being collection only and not wanting to box it up and post/wait for courier "why not? - they're insured" etc etc. In the end I cancelled and refunded him.

So to get to the point - how do I stick it back on Ebay but stop numpty#1 bidding/buying it? I cant be doing with the mither!
