Long build you are not quite correct in what you are stating ....it is not the addewss that is banned at all.....it is the Email address linked to that seller that will be banned THATS all....Change the email addy and you up and running again.
HOW do I know well I had to do it.
I sold an iten to an IDIOT of an Australian....ok NOT all of them are IDIOTS

He started a pay pal claim 5 days after winning as he had NOT recieved his Item..... Ebay strike given as HE did not close the case Judgement against ME.
And he STILL has the goods FACT
Bought some bits off an ebayer left Neg feedback as goods were Pants got money back.....Mnths ltr he bought £1500 worht of Motorsport goods off me...never paid started Dispute.....got police involved he got prosecuted for trying to get goods by Deception case never closed Ebay Sided on HIS side another strike given.
A Mnth later he bid under another Ebay name and did the same Guess WHO was stopped from selling YES IT WAS ME.
I have had him thrown off Ebay 15 times so far funnily enough yet again TODAY and he still manages to come back.
As I did not have a selling account and needed one I looked into beating the system and ALL you do is to start again with a new ID new email addy and away you go.
I for one would like to be able to see who you are bidding against as it was so so easy to trace a friend of a seller who was Bumping goods up Now you can not .
