I'm going to go over on how i feel about this.
Q:Should we limit the accessibility to the fandom work Guyver Advocacy has done for Guyver fans?
A: No, I feel that that would destroy the purpose for which this site was built.
Q:Should we add more copyright information to the pages, like watermarks, URL's, and disclaimer of distribution?
A:Absolutely, this should of been more thorough from the start since someone took the work and is now possibly generating a bit of revenue off this. This is the nature of the internet, and in turn you should expect another couple of sites to follow up in making duplicate postings. Closing down the site or other drastic measures would have little effect since there is now a copy online of all this work thanks to spectrum. It should of been expected. Even if spectrum was taken down too, someone out there would have it, and even search engine spiders have a copy image already.
Q:What should we do now?
A: Carry on, this is normal. Doesn't make it right, but it just means we proceed and enjoy what we enjoy, it's not like we actually own the franchise, it's just a matter of being more careful on how we release updates. Granted they will likely take the updates, but now we know what to expect and can have a properly prepared page setup for dealing with it.
Q:What will happen to Guyver as a result?
A: As frustrating as this is, it actually works out for us in a way. If Guyver Advocacy's work spreads to the most popular sites, this in turn spreads Guyver's awesome manga plot and increases a fan base for a franchise to a new generation or a group who thought it wasn't continued. This may of been a shameless theft of fanwork, but it's also a chance for us to spread guyver, and with the URL's and digital imprints, we have a chance to attract more fans here.
Q:What about Spectrum?
A:Honestly, I don't know? If you want, contact them and tell them we are unhappy, or ask them how they came about this sites work? I think an apology would be in order. i would like it if they would ask permission as well, if they do ask it wouldn't be too bad to let them host it, though i'd like to know if they make money off the work, in which case we shouldn't let them. Another problem is if they don't care and do what they want, but it's a matter of how communication would go. You can probably look up spectrum's webmaster if you want to really get down to the source of the site.
