The uptick I've noticed (Score: 1) by fishybell@pipedot.org on 2015-10-23 21:09 (#REBZ) The uptick I've noticed is websites serving ads from their own servers, with URLs that are very similar to their content. I've had the experience multiple times now where I go to create a new block filter and the URL is something like "www.example.com/images/3582351294521.jpg," and all of their visual content is along the lines of "www.example.com/images/3392354894900.jpg." I'm left with the filter "^www.example.com/images/.*" (or creating a more complex, and my-time-consuming, filter based on the html entity containing the ads) and everyone loses.The more websites that follow this tactic, the less useful ad-blocking filters, as they are designed today, will work.
