Also, since they are fixing your deliberate choice to ignore how A is supposed to be formatted, yes I have seen you argument with an Admin on it, they can also tweak the coding format if need be without issue.
Yeah, I've been meaning to clean up external links, but without a good bot script, it's going to have to happen manually.
Basically, they're a relic of the early days, when content was largely copied from other places to serve as padding. That's why the links are old - nobody cared enough to updated.
ComicVine should also be removed/not be added. Comicbookdb and comics.org are a bit different, as those are primarily indexing sites and do not have character profiles.
Those Who Ride The Lightning and Titans Tower are early, pre-Wikia, sites that the early editors liked. There isn't really a concensus on what to do with them. They're still good in terms of content, and I don't know what other admins think of them.
The Templates > See Also Template > Template:_______Links each contain a variety of links mentioned above and other links. Plus, Wikipedia links to the same page that is already linked through the (| Wikipedia = _________) i.e. doubles.
Even after I type this I'll probably recall other links that are Go/No Go links.
