For those of your running sites where users can upload images, how do you deal with preventing spam and offensive content?I'm also wondering how to deal with all the regulations surrounding this: legal liability for copyrighted content uploaded by users in Europe (where our team is based), DMCA takedown notices in the US, or the site becoming a distribution channel for adult content.Are there any automated solutions for content moderation that a small team can employ? Or do we basically hire people to moderate all user uploaded images?
