Good Evening All
As we have pointed out numerous times, it is entirely up to the author (or copyright owner) of the artwork to decide of their artwork is being used without permission. If you believe that someone is using another creator's work without permission, then please contact the creator and they can then contact us directly. Copyright law is relatively clear here, only the owner of the copyright can request their work be taken down. This is pretty reasonable, as only the owner of the copyright, and the person using the artwork in question, can know if permission has been granted. Anyone else is either guessing, or at minimum is a 3rd party who may not be aware of all of the facts.
I know a lot of people may not like this, but this is to protect all parties. Otherwise it would be very easy for someone with a grudge to start having content removed, members banned, and so on. Unless you have access to the email accounts, letter boxes, and any other communication channels available to both parties, you really cannot know for certain of the artwork/content/etc is being used/etc without permission.
Unfortunately, if the owner is unwilling r unable to contact us we may be unable to act. This can be taken on a case-by-case basis. An example is that it is well known that LandLvr (apologies if I have spelled his username wrong, it's 1:30am!) allows his content to be redistributed via email, but does not allow it to be hosted on a website. As such, we can take some action here (e.g. removal of download links from the forums). But, only LandLvr could request the server host to actually remove the files if it came down to it.
As to piracy of content (e.g. redistributing payware, or even freeware, content without permission), please report any posts that relate to this for our moderators to look into. I'd suggest stating that you believe the poster is pirating content so as to ensure our mods are aware of what the post relates to. As always, the action taken is up to the moderation teams discretion, but we try to keep on top of posts of this nature as much as possible. I'd also recommend reporting this to the creator. If they can confirm this then we may take further action in relation to the posts.
Regards
