Okay, so just to dig up some skeletons and re-hash the previous "you can't prove you hold the copyright to use samples / acapellas" conversation... what I find flawed about this statement is the band page for Turmion Katilot.
So what you're saying is you've either traced their IP's to shit and found that the computer uploading this band's copyrighted songs is actually in Finland or Germany, or you just don't care enough to give a second look to the fact that somebody - potentially just a fan having nothing to do with the band - is uploading copyrighted material.
So what you're saying is, I could make an account, type in broken English, post some tour dates on my User Blog, and bam, I'm instantly the copyright holder for a band's songs? Yet... I'm prevented from using samples that are held in a Creative Commons law from a well-known band, because I didn't make them. That's awesome.
And what's more is... you'd figure if any audio mod here was worthy of the title, this issue might - just MIGHT - have been addressed a little sooner. I mean shit, if I was an audio mod spitting out rules about how you can't use a sample that's licensed under Creative Commons, and just happened to stumble across a "band's" page filled with copyrighted material, you god damn better believe I'd be asking for some contracts faxed to the Newgrounds offices with signatures with every single copyright holder, a contract from the record company saying it's okay to release so-and-so-band's music on a site that only holds a creative commons license (which we normally charge $1 per download, but hell, put 50% of the album on a flash site for free download), and then I MIGHT not blam the shit out of their account.
So in all your flawed logic, Mr. Incorporated, you're saying any user that uploads their audio to Newgrounds is instantly putting it up under a creative commons license, and it's perfectly fine to use THEIR samples or remix THEIR song, so long as I give credit tto the original author? So if I remix and sample the shit out of Verta ja Lihaa, which is a completely copyrighted song, contracted under a major record company in Europe, it's fine and I won't get banned or deleted, because they uploaded it to NG and that automatically nullifies any pre-existing contractual agreements they have with their record company about distribution? For all you know, their record company may have just found out about them distributing their audio for free on Newgrounds account, and are preparing the paperwork to sue the shit out of NG, as you said previously. Fuck, for all you know, it's some 14 year old fanboy.
