When creating a post with a URL, Lemmy generates a thumbnail with the og:image and a text summary with the og:description. And sure enough, sleazebags use the description field to plug products.

Case in point: this Youtube video. The description should be something like Man creates a pair of glasses in titanium damascus - part 2 but instead it says This Valentine’s Day good things come in big packages at MeUndies. Score huge sitewide savings at https://[redacted] and use promo code forge.DISCORD…

It’s really aggravating. I don’t want to pollute Lemmy with crappy advertising.

Is there some way to override or suppress the text description?
