Please add a new section under "for Users" in https://fedecan.ca/en/guide/threadiverse/overview about the lemmy.ca sitewide blocked instances and reasons. Don't need to list the reason for every single blocked instance but can call out the more noteworthy ones that had a discussion.

Why I'm asking for this is I was trying to subscribe to some communities from lemmit.online but was getting a terse and confusing error. It took a bit of digging to see it was intentionally blocked from lemmy.ca and the reason why.
