The suggestions in their direction for future improvement section should be implemented sooner rather than later. There's no point in growing this platform if it's going to be left wide open for abuse like it is.
I also think, in lieu of lemmy devs making any improvements, another good solution would be for a third party to prop something up that scrapes every lemmy post and runs it through an automated service for detecting known CSAM. The third party service would be forcing at least one of those future improvements on lemmy, as it exists today. Any known CSAM that's found would be automatically reported, and if the instance owners can't deal with it, then they would rightfully have to deal with the consequences of their inactions.
Edit: I'm beginning to think reddit was maybe not so bad. Getting mad about more robust tools for moderating CSAM is just sad.
