So you'd block all canvas elements if ads are always a <canvas>.
If they turn all their posts into <canvas> then it'd kill any accessibility features and the ability to copy-paste text and such so I doubt they'd go that far.
Even then, a scraper could run OCR on the canvas image to get the text out of it.
