yeah, sad that people have nothing better to do.
regarding your banner, the way i understand it, branding is okay on ebay to a degree, as long as the .com isnt on there and links to Me page or ebay store instead of to off-ebay site.
Their rules are clear as mud, but here's the way I read it: Me Page can have link to off-ebay as long as the site it goes to doesnt offer items from multiple sellers, cant directly offer items off-ebay (cant say "click here to get coffee mugs", etc), and cant offer same items off-ebay for less than what you sell it on ebay.
