Nitpick:
Please consider using a full link macro here.
link:http://fedoraplanet.org/[Fedora Planet]

Not a big problem, though, as URLs beginning with https:// (and other standard prefixes) are automatically parsed by AsciiDoctor.
Please feel free to ignore this nitpick:)

I'd personally avoid contractions (Ln#8) and Saxon possessives (Ln#9).

What would this be referring to on line 24?
Filtering your content? Setting up a feed of your content to Fedora Planet? The wording seems slightly ambiguous in this paragraph .
Please use pronouns with caution:)

I'd be inclined to use 2 words: plain text as opposed to plaintext, because:
1. plain text appears to be used considerably more often in technical writing.
2. plaintexthas connotations related to cryptography, which do not apply to this context

@ssitani Thanks for the feedback. The latest commit addresses all of your feedback. Thanks for the nitpicks. :thumbsup:

I could easily see this turning into a bullet list htat just lists the content i.e.

• sexual images ...
• copyright violations ...
• other material which violates the CoC

no need to explain why.

WDYT? CC: @mattdm

I don't know if we even need a list. Actually, I'd just remove the == Inappropriate material and put "Inappropriate material may be removed from Fedora Planet without prior notice." as the last sentence of == Appropriate material — that section already references the CoC.

@bex @mattdm I made a new commit based on your feedback. I opted to remove the Inappropriate content section, moved the disclaimer about inappropriate content, and renamed Appropriate content to Content guidelines.

Unless you're referring to the Your Name placeholder itself, I'd use a regular font as opposed to bold. If you'd like to designate a placeholder inside the code block, you might prepend the [subs=+quotes] attribute
