Yea. As a server admin with 18 years under his belt, here's the first thing you need to know about the internet. If you have an anonymous service a basic tenant is moderation and spam fighting. I've seen a hundred good ideas that would never work because they don't take in to consideration that 'People are assholes'.<p>Any system that does not fight spam will quickly become only spam (porn considered as spam in this case as it's not the point of the app). Any image rating/manipulation program will quickly become only spam and porn unless heavily moderated.<p>TL;DR: If you aren't considering spam and security issues when developing apps please stop. Either read up, in detail, on how to do it correctly or add a developer that understands the issue.
