The fact that it’s going to take time is understandable.
But in that case images need to be banned until the solution is found. It simply cannot be done by trial and error.
TBH I imagine that MN HQ believed that they had found a way to mitigate against this hence why image uploads were re-allowed. But now this has been shown to not be the case. Although I’m not entirely sure how you test something like this because it’s not as if you can put it to the test by feeding it said images to make sure they’re blocked. So it may actually not be possible to block these kinds of images other than to ban image uploads altogether.
TBH this kind of thing isn’t unique. Not just CSA, but you only have to look at other social media to see that inappropriate content is constantly being uploaded, beheadings of e.g. Saddam Hussain were up on YouTube when they happened and that was more than a decade ago. That shooting in NZ where the terrorist did it on fb live, people upload images of car accidents and dead bodies and so on, and although most platforms do remove that kind of thing fairly quickly, it’s an issue that they’re able to be posted there in the first place.
In truth the only way to prevent harmful content being uploaded anywhere would be to ban photo and video content linking full stop. And there’s just no appetite for that, not least because the majority of content uploaded online isn’t of such a heinous nature. So this kind of content is only likely to become more prevalent, not just on MN but on the internet as a whole.
The online safety act already makes it mandatory for content to removed as soon as possible. if this kind of thing continues then it’s likely to have to be extended to penalise platforms who allow these uploads in the first place, is what will kill online uploads, as sites simply won’t allow them.
Edited because the last bit didn’t look right.
