You can accept BTC through eBay as long as you also accept Paypal or other eBay-approved methods without prejudice. Of course, that probably doesn't do much good because most eBay buyers will use Paypal.
Do not even mention bitcoin on e-bay ,you account will be flagged and you will have your items removed for various breaches ,I personally got my items re-instated once I removed the word bitcoin accepted from my sale items .
Even my listings that did not mention bitcoin got taken down in the rush to get my listing off e-bay.
I got an apology from them saying some of my items were taken down by mistake but none of the listing containing the word bitcoin were re-instated .
Took me 2 weeks to sell some oil on e-bay ,it normally takes 3 days to sell .
I can only comment on my experience .
If you contact customer services you talk to filipino people that do not understand English ,I spent 33 minutes and was passed from 7 different specialists before being told there was nothing they could do for me to get my listing up again .
