Actually there have been a couple of lawsuits in Germany that changed the practice locally: https://www.lexology.com/library/detail.aspx?g=12d4d756-d753...

Now most are very careful and even "overdisclose" advertising as a result (they disclose even for products they mention that they are not paid for it).

Even on HN I've pleasantly told people to please disclose affiliate links (that I've only found out about because I click them and uBlock blocks the page from loading completely due to malicious amounts of tracking scripts) and people get upset about it.

I wish they would overdisclose here. It does not help that on social media, lots of people think adding "#sp" is enough.

If they're American, merely adding #sp is an open and shut violation. That should be reminded of the consequences of failing to disclose
