I've had work in the past posted to their site without attribution and it was a headache to get them to either attribute it or remove it (they chose the latter).
It seems rather obvious why their Facebook account was disabled.
The DMCA law establishes processes between content creators and websites, but leaves websites free to determine the processes (or lack thereof) between themselves and the users who submitted the content. I.e., a single photo can result in termination of your entire fanpage without warning.
As more and more people rely on companies like Facebook, Google, etc. to host their content, consumers are going to need protections against arbitrary actions by companies, lacking due process.
> lacking due process
Due process is a constitutional right that only pertains to citizens' interactions with the Unites States Government and state and local governments.
Just as folk were then free to set up their own press to churn out leaflets, so too are folk now free to host their own content. In fact, the situation is probably a lot brighter now.
And that, folks, is why you at least attribute your sources. I feel no sympathy for a company who has no compunction about posting others' work uncited/unattributed much less even uncompensated.
Facebook said we had posted inappropriate content but I was the only one with admin access and I'm absolutely 100% sure that never happened. Also the page was set up so users couldn't post images.
I think what must have happened was they had some kind of temporary exploit where someone was able to post inappropriate content that looked like it came from us, or maybe users were able to post something temporarily somehow. Or I guess it could have just been a glitch and nothing bad ever happened at all and that's why they reinstated it?
It was very stressful but I'm glad it's over now.
I think that something similar (they banned our whole domain) also happened to us last year (http://news.ycombinator.com/item?id=2527955), and I still don't know who fixed it or if it was just a glitch.
You will note that I've used a lot of "I think"s, there's a reason for that, nobody (except for FB obviously) actually knows the rules of the game :/
Even before we were mysteriously blocked I never let users post photos/videos to our wall and obviously we'd never allow any inappropriate content there.
