These ones really annoy me:
They are obviously a scam! Earlier in the year My ebay account was hacked onto, and about 20 of these type of adverts were listed though my account, Ebay charges came to over £150!!!
Luckily I contacted ebay quickly and they had the adverts deleted within 24 hours and the charges removed.
The surprising thing was people WERE emailing me!!! I had to keep telling them it was a fraudster advert! Although it was tempting...
