I'm an arachnophobe. If people reliably put "cw spiders" on links to spiders, my life would be a bit better. (Not a lot, because it's already not that hard to avoid pics of spiders online.)
What we're talking about here isn't 'may contain nuts', it's 'definitely contains actual nuts'. This link doesn't have a "chance" of seeing a stuffed goose with an arrow in its neck, that is in fact what is there. Your example doesn't fit.
