One of the YouTube channels I subscribe to is Techmoan, hosted by an English fellow named Mat, whose videos mostly present his thoughts on various electronic products, including long-since-discontinued and/or esoteric and/or whimsical audio equipment. (Here's an example that covers all three categories.)

He recently posted a video that included an aside on the topic of being called a shill in comments under some of his videos. He explained his position on the topic and finished by saying, with reference to the product he was reviewing, something like "So ignore whatever else I said about this item. Whatever you do, do not buy it. Repeat, do not buy it."
