In general, faq posts here on MSE are community-curated, which means that as the system changes, posts can become outdated until members of the community bother to edit them. (This was something that I worked to fix before joining the site.)
However, I noticed that the FAQ on bans and the quality filter, What can I do when getting "We are no longer accepting questions/answers from this account"?, is locked to prevent frequent off-topic comments. I can understand that too many banned users commented about their bans, which necessitated this drastic measure, but this prevents the community from making edits.
Ideally, this feature request would be implemented, which would allow editing but not commenting. (Don't worry, banned users wouldn't be able to suggest fake edits to contest their bans; as the question is locked, suggested edits to its answers would be prevented.)
In the meantime, given the current status quo, what's the preferred way to have edits made to that FAQ? Currently, only SE employees can edit it, due to the lock, but I have several changes in mind that I'd like to make. Should I ask a new question for every set of changes, such as FAQ not mentioning allowance of one question per 6 months during question ban?, or can I just flag for moderator attention? For a larger edit, is it acceptable to give a link to my proposed Markdown on an external site, such as GitHub Gist or Pastebin?
I'm looking for an official answer from staff about their preferred way for my making such edit requests, if any. I'm aware of the comment from the moderator who locked the answer initially which says to flag, but that comment from 2012 was posted by a Trilogy moderator at the time when they were given moderator access on this site, and I'm not sure if that's the preferred way that SE would handle it. I'm also leery of this, since many of my flags have taken a very long time to eventually get handled.
