This does seem like they're trading long-term trust for short-term profits - users will click on fewer and fewer sponsored posts as the number of deceitful posts like this increase.
Often marketing platforms (like Hubspot or whatever) lets you create multiple landing pages which might all be on a subdomain(s) to rather than handing full control of the root domain to the platform. In these cases, you wouldn't want pages.ctvnews.com to appear as the display domain.
Also not to mention the myriad of services and ways that act as a middleman for the click, in the same way that the link display on Twitter appears as ctvnews.com but it's actually a t.co link
Marketers can buy domains if they won't want to display a sub domain, and Facebook can check the final destination landing page. I mean, they already do! Every time you make a new ad they scrape the final destination for meta tags and content.
I'm saying they should have to suck it up and buy the domain they want to display.
It looks like Facebook host a lot of ads themselves, so I guess that advertisers use URL shorteners as a way to verify click throughs from Facebook.
For unsophisticated advertisers (i.e. with no referrer log analysis) I guess it's pretty easy and effective.
In that case most advertisers are unsophisticated. Even the biggest ad-networks/retargeting/tracking solutions all depend on redirect via their servers to their end customer.
I am constantly disappointed with the technical knowledge and understanding display by our advertising partners. A large number of them have almost zero understand of how the internet work. Of cause part of the problem is that as a developer you're inclined to point out that something won't work because it won't work 100% of the time. That a useless answer for the advertising department and you end up with duct taped solution that works well enough, but of cause create their own set of problems.
I secretly suspect they -at least- know, but prefer to sweep these issue under the rug and that's why they prefer to involve as little technical people as possible. And that's why I don't work in this industry anymore and I won't come back to it until they've all burnt to the ground.
The fix is super simple: Their tracking pixel receive our order number, all they need to do is accept that it's unique and just tracking the first occurrence. Part of their problem is of cause that they switch to a new platform and didn't migrate any data.
Because many of the amount are so small, they just accept a ton of errors and as you say: "sweep these issues under the rug" because it's just a few cents so who cares. But it adds up.
Bait and switch scams have existed since the dawn of time.
