Web traffic stats are a wonderful thing …
A Polka band not only stole an image from one of my sites, but linked to it directly, pulling the image off my server ever time someone visits.
So I swapped the graphic, making a new one with the same name and location. Yes, I was tempted to make it slightly pornographic or at least inappropriate, but instead, I was “nice” … and they’ve had the “new” graphic all over their site for weeks now. They don’t even know, or are clueless how to fix it.
