- Stolen: The generic 'RO' on the end of every server name.
- Stolen: Gravity's sprites, textures, maps, and scripts.
- Stolen: Art used on loading screens/patcher/website, taken from Gravity or some unsuspecting fan artist.
- Stolen: The copy of Photoshop that was used to abuse the stolen art.
Hmm... you can't really call it stealing when there's absolutely no legal mechanism to protect against it. Apple can't patent/copyright "software program names that begin with non-capitalized 'i'" any better than Microsoft can stop third parties from using the word "Windows" in their product names. Yes, words like "Macintosh" or "Microsoft" can be protected, even "Ragnarok Online" can be, but... "RO"? That sounds to me as generic as "i".
It's hard to say you are stealing Gravity's artwork and sprites when they freely distribute the client and let anyone download it

Isn't that kinda like leaving a big RAR file full of your work on a public ftp server and then complain that those who download it are "stealing it" because they didn't use the file as you wanted them to? (doesn't that argument sounds silly when said this way?)
I can't argue against Copyright violation (point three), but not every server engages on that (eg: I am pretty sure I don't).
I have never used Photoshop, there exists alternatives (like the Gimp) which may "not be as good" as the real deal, but you don't really need it (most people really don't).
I've seen this topic before, a long time ago in the eA forums. :v You know that the only real illegal activity, is breaking Gravity's EULA when you hex and distribute a modified client? (but even that might be contested some day, as EULAs aren't really enforceable, at least it hasn't been upheld in court yet).
