I'm far more wary of the fake adverts on YouTube if we listing complaints comparatively and I'd warn people of that far more and sooner then any promotional deal thats ongoing with streamers etc. and fairly obvious in comparison. The adverts on YouTube are frequently fraudulent and just lies, selling made up products that wont ever do what occurs in the advert. I even get a scam warning from anti virus software quite often if I click on a YouTube advert to warn me this website has been reported as fraud based. I click because it supports the content creator not because I'm prone to believe the lies spread during the advert. YouTube adverts have got increasingly worse, it needs to be said they are openly scamming people and it would be illegal if on TV. On the other side acting as a promotor for casinos is relative open and fair game imo.
I dont see why people kick up a problem especially, watch or dont if you dont like it.
If you scale that, then you are right, there are more paid promotions being advertised inside YouTube.
Not the streamers, but the site itself who provides those paid advertisements to those viewers who are not careful, for sure they are endangered
following external sites, believing that it's legit since YouTube allows them to promote.
Minding yourself from those fake streamers or advertisement is very important to lessen the chance of being allure and lose your money.
