It's funny, I read this thread this morning before I left for work, and I composed a literate and witty reply in my head while I was driving.
There was traffic on the highway, and I had more time than I thought.
Anyway, by the time I got to work, it was locked.
Now I feel as if this thread has jumped the shark and my reply is no longer really necessary.
I will say, though, that I agree with Jade that a having a second RP character with a different agenda than your main character is entirely legitimate. I have one, and I usually refer to him as my 'second main' rather than my alt. They can be used to create good and dynamic stories. I think Ms Shaw is clearly different to Jade in that she is clearly played with a dry, satirical sense of humour, something I don't think the character of Jade has. I don't see a problem with this.
On the other hand, I think it's disingenuous to cry foul about the OOC/IC divide on Sabbot's actions. Accusing another character of being an alt is something your character could not possibly think, and always breaks that true IC immersion that many are going for.
The thing is, it's either alway wrong, or always okay. The use of links and web traces or whatever does not enter into the equation. It's no different from other occasions of people (and not just Jade, mind) doing the same thing with others.
Sorry, that's only the beginning of what I'd planned to say, but there's no need to inflame things further. This SF vs the Rest mentality that is developing in the RP community is not really helpful, in my opinion, which is why I tend to leave their IGS posts alone.
