ok seems I can't log into my email accounts these days without finding one of my listings automatically removed!

this time I have to google the email address ebay sent me to work out what Id done wrong..apparently its a copyright issue with ugg boots.  so can someone enlighten me.... I can't resell a pair of preloved ugg boots. .... and that is because?    

I mean so I can't resell many of my sons preloved clothes due to copyright laws?  I don't get it.! first particular coloured dolls from the 50s then cow bone (ok I understand that one) but not a minimal cost listing that includes my 3yr olds slippers?

"The rights owner or an agent authorised to act on behalf of the rights owner, ............................., notified eBay that this listing violates intellectual property rights. When eBay receives a report of this type of violation, we remove the listing to comply with the law."

Its not even so much the ugg boots I'm concerned about its just if I list other brand clothes eg quiksilver pumpkin patch etc how can I avoid the same response?  so I can't resell now??
