The problem with a list like this is that a “bad website” is in the eye of the beholder. I’m not saying that there’s anything wrong with you personally not liking the Shopify or the Semrush blog. But I think that everyone else has their own calculus.

It’s the same reason why social media blocklists can be problematic—everyone’s calculus is different.

My suggestion is that you promote it as a starter and suggest that users fork it for their own needs.
