I don't know who you are Mr TooMuchEspressoGuy, but I know you're out there, and I hope for your sake we never meet my friend.
A unique sig on SlashDot is like a 4 letter domain name or an e-mail like email@example.com, let alone a unique Star Wars-themed sig on a news portal with nearly 1 million geeky users. They are treasured things and command a hefty sum on Ebay.
I don't care that the actual text was stolen and somewhat bastardised (I'm not going to invoke the DMCA on your arse). What I do object to is the misrepresentation that you in fact created the sig. So not only do I have to put up with my sig no longer being unique, I'm no longer attributed with its creation.
This isn't a copyright or an *ughhh* "Intellectual Property" dispute. A sig isn't like a piece of computer software: it is an expression of one's personality; of one's uniqueness. I couldn't give two tugs whether you use it on some forums, as your MSN alias or as your gorram e-mail signature, but on SlashDot this sig is unique to me and I take offence to that. So if you are to continue use of my sig, I request that you give proper attribution, linking it to http://slashdot.org/~BlastM under the title of "Sig Author".
Comments are enabled, so TooMuchEspressoGuy, I invite you to present your case.
