That type of advertising should not be acceptable, full stop. Thanks for letting me know that eBay was behind it though - it gives me a(nother) reason to avoid using them in future. I'd second this point of view - even though I never saw the advert, it provides further justification to those of us who refuse to accept ads, full stop. I even go as far as to boycott advertisers on those (very rare) occasions when I do enounter intrusive advertising - whether online or on other media. It's an approach that works well since almost invariably, the most heavily advertised products/services/companies are those that offer least value for money. True bargains have to be searched for - and you have the satisfaction then of supporting companies that aren't responsible for polluting your online experience.
