That depends on the scale though right? Reddit ads were for a long time very poor. They've become a lot more feasible for many companies in the last few years, as Reddit has also become a lot more mainstream.

Also we don't know if they are doing basic fraud mitigation. It's possible they are doing plenty of fraud mitigation, but that it's just not advanced enough.

Did you look at the link? The detection methods used, and the discussion of mitigation in the thread, make it clear that if they are doing any mitigation at all they are neglecting obvious red flags.

Every business is obliged to be ethical, vigilant against deception, and not blatantly lie, no matter what size they are. Even if you could make an argument like this, reddit was already pretty big ten years ago. That's why they started running ads.

I wish they would actually address this issue in the OP's link. None of the reddit ad reps have responded to this and it's quite a shame they haven't yet...

Their ad "platform", i mean the page where you go to buy an ad was a joke until very recently. broken images and stuff. a kid could do better.

Not that they need to change, i like the simplicty of their ads
