Great suggestion, @klye. I touched on this a bit earlier stating we should be properly tagging NSFW content. However, that's not a complete solution right now when the tag has been buried.
Downvoting is a toss up for me. There are some posts that definitely should be hidden, (i.e. harassment, bots, etc) but when it comes to original content, or "explicit" images, there is also a fair amount of people that want to see that.
I think @timelapse's idea is great. Click to consent, a warning, or a tag could be an easy fix for situations like these.
Here's to future updates that will make everyone's experience better! Cheers!
Crappy circumstances.. Still unsure why this was done in the first place to be honest.
