I'll be blunt, I care a lot more about Dark Souls and correct info being out there than any single community.
This is why I don't have a single home - I make a lot of edits to the wikid0t directly, but I also post about a lot of my findings on this forum with the hopes that someone can corroborate my findings and contribute them into the wikispaces (I'll elaborate on this in a moment...). I also post a lot on r/darksouls, and more recently the gamefaqs as well.
However, this doesn't mean I intend to disrespect any community. If it's considered faux pas to link to another wiki here, then perhaps it should be made against the rules, or filtered to be blank. I think filtering it to change into wikispaces is a weird, sort of sneaky way to pretend that other information isn't out there that can be used to better knowledge across multiple communities.
Why don't I just edit my findings directly to the wikispaces? Actually, you will find me doing just that, very soon.
Hopefully people understand my perspective, though. When I first started making edits to wikd0t, it was an arbitrary decision simply because I was more familiar with it from the days of Demon's Souls. At no point was my intention to avoid contributions to wikispaces.
However, here's where things become questionable. At what point would it be unacceptable to copy some pages or sections verbatim from wikid0t? I think most people would say that shouldn't be done, but what if there's a page I wrote completely on my own, or a section where I personally did all the testing? It wouldn't be copying wikid0t, it'd be copying myself, but I was still little worried it might look a bit shady.
Which is why I've been trying to use a temporary solution - post about my research here so others who do contribute to wikispaces regularly can corroborate and contribute it themselves. I'm not trying to hoard my findings, I'm hoping to share them.
This type of cross-community collaboration can be excellent. I had a great experience with Ublug here, where we worked together to solve the mechanics of obtaining soft humanity. In its initial state, wikispaces had preliminary info about it, wikid0t had none. I was able to get a bit further, learning a bit more and correcting some information about the mechanics--- only to get stuck again myself. This is where Ublug came up with an improved and correct point system, allowing me to get unstuck and learn even more, to the point where we solved the whole thing together. Now both wikis have a complete and accurate explanation of this, in their own words, which is exactly what I want to see.
The point being, I'd hate to see this kind of encouragement of shutting out other communities. Working together would be for the benefit of everyone. Sure, if someone goes out of their way to excessively link to other wikis out of malicious intent, that is incredibly rude. In all cases? I'd argue not.
All that being said, I'm still going to sign up and start contributing my findings directly. There's a decent amount of stuff I can correct and put in without obviously creating content similar to other pages already out there, so I'll start with that.

And this post was made while the other responses were written. I'll have to respect your decision. I made a request, request denied, I can accept that.
