If you are asking for my opinion on the SCP Foundation being on our wiki, my opinion remains the same that it is at best extremely tenuous and vulnerable to being influenced by our wiki- whether directly, by our users writing stories for it, or indirectly, with our lingo and jargon seeping into it (whether that would constitute proper contamination may be a matter of opinion- in my view, it could). I've never stated my opposition to SCP to be rooted in seeing it as "illegitimate"- my issue is with how easily one could manipulate it (and as I've pointed out, I know of at least one VSBW user who has indeed published their works on the site successfully).
Collaborative fiction isn't inherently flawed like this- there are numerous universes featuring multiple authors writing of their own agency: the Cthulhu Mythos springs to mind, with many contemporary writers still contributing. Other more franchise-focused works also feature multiple authors hired by their corporations: Warhammer and D&D both feature multiple authors often working on the same line of novels, not to speak of the overall universe. My problem is not with collaborative fiction, it is with the level of access that is granted. Anyone can submit anything and it can, feasibly, be made canon (and thus usable for the wiki).
So, just to confirm: I'm still anti-SCP.
