Yes, they still hunt from time to time and actually used a numb nuts third party to bring stuff down, which is complete BS as they put in the IP take down request when they are not the IP owner.
No, ebay doesnt care and will not reverse the take down regardless of the validity of the first sale doctrine on these items. So, if you get 3, your account gets locked down for a month, been there.
If they get one of your items, you might as well end all your FOX items as they will nail them all and will watch your account. Personally I think it is other sellers that send a mail to Fox, but maybe that is just me being paranoid.
