In regards to an earlier version of the last reply, not all pages on Community Central are protected. The (main) namespace has been closed off from editing, but most help pages are free to edit, and adoption requests are free to be submitted, just like bot scan requests. There are quite a few that have been protected, especially if they have endured vandalism or non-constructive editing recently or if they are high-traffic/fundamental to the entire platform.
I know Mendes2 already addressed this but I just wanted to give what I think is a better answer. Certain wikis such as Community Central are exempt from the rules about page protection because of the important roles they play for the entire Fandom network. For example, the help pages here are used by all other English Fandom wikis. Therefore, vandalism here would have a much more severe impact than vandalism on another wiki such as DC Database. Basically, any wiki created by Fandom for administrative and/or support purposes is exempt from this rule. All other wikis are not.
