There is a substantial amount of spam and NSFW posts on the All page coming through already. Most NSFW posts aren’t being tagged as such and are coming right through. I am not sure how this can be weathered but we need something in place fairly soon, I feel like we are days away from rivers of bad stuff, especially via some of the federated instances.
EDIT: I personally don’t care much about the NSFW aspect, more in the lines of what a newcomer will be seeing when they get to the main page. 99% of the newcomers don’t know / care about federation and have no idea how to turn that off. Liability for the server owner is also an element of consideration.
I have “do not show” checked, preview media off, and I have yet to notice any of these images blurred since they’ve started popping up. So apparently no one is marking their posts appropriately. I don’t care about the porn itself, and can certainly block it if it’s one source spamming, but like many here I’m worried about the newcomer trying to figure it out and getting a first impression that isn’t all that great.
