Some users here (one of whom I'm posting this on behalf of) are nervous about posting feedback to this site, because despite the anonymity of being able to make a suggestion, it's impossible to provide a message in response as a comment.
That anonymity is worthwhile protection, because e.g. a user can be afraid they'll be bullied out of participation. Indeed, people who bring up feedback can express a lot of strong response to it, and might find discussions about it outside of feedback unavoidable - or at least, may feel that way.
One could create a new anonymized character, but that can leave us vulnerable to posting as the wrong character incorrectly, or leave our feedback comments vulnerable to being wiped out if we need to do clean-up.
TLDR: When we post a reply we should be able to post it as just "Original Poster" rather than just a character.
