I saw someone else doing something similar - hotlinking images of an item which they were selling for maybe $50. Well the owner of the original image replaced it with "$30 at whatever-store.com" So you open up the auction, are greeted with an opening bid of $50, and a picture telling you where to buy it cheaper.
Aah, the dangers of stealing.🙂
Someone was hotlinking to a 152KB image on my webserver, and using it as a background on her site at Myspace. I was nice and replaced it with something saying essentially, "Don't hotlink" - she's now hotlinking to a 400KB image on someone else's server. Guess I should have either explained "This is what hotlinking IS. Now don't do it."
Or used obscenity.
She's totally ignorant as far as making good sites goes. She's got an auto-start audio file in the page - that, along with the huge background image, her page is over 600KB.
Hotlink - bad. HUGE background images - bad. Auto-play sound - bad.
To the OP: You could replace that animated GIF with a PNG file (smaller than GIFs🙂) saying outright "This user steals images and coding from other eBayers."🙂
