Have got fairly good at spotting these from the first few lines, but it would be nice to not bother clicking on them in the first place & better again if they didn't clog up my search results.

Back when it was just humans churning out rubbish, there was far less of it in the way of good information, but it helped enormously that search engines still respected operands.

Bringing that back would likely help far more than a detector extension.
