Look, Google even controls YouTube ads very well. The problem is that often what is advertised, there is nothing wrong.
I can create a YouTube ad, and just say, "I can tell you four ways to make money, easily and effectively. Don't miss the opportunity to increase your income and have what you love most."
And then the service I provide is to refer people to websites or services that allow people to earn money through work or investment.
This is not wrong, nor is it a lie. But it really is a rogue scheme, to take money from people, about things they already know.
Unfortunately this will be difficult to eliminate, and for Google to ban. Then, it may not even be in the ads themselves, but in the videos on the platform, and in that sense it's even more difficult.
But we already have seen many ads that will not be like that. Even some ads can be misleading the audience by saying, "I am making a thousand bucks by doing this simple thing."
Google will hard to detect those ads as it needs more inspection or monitoring of their ads but they can warn the advertisers from the audience reports. If they still do not obey the rules, Google can ban or block their accounts and not allow them to use their site. But that will not stop them from creating new accounts.
Google couldn't control or stop ads like that but we could still do something to get rid of them. Since they're targeting players to bet or to spend too many funds, we should also take responsibility by being skeptical and observant of different ads that we may find online. Scammers are over the internet so we should always be wiser than them.
