Have you ever personally been bothered by feedback you have been given through the accept/deny thread?
I've submitted very few RPs in my years here, and I'm fairly certain that none of them have been denied (that I can remember), so my answer to that is no, no I have not.
But on that note, if we were to keep the list of who's accepted/denied, but start sending the reasons for denial over PM, I think it would become
more embarrassing to have just a few simple mistakes like forgetting to add a rating, unless small errors like that remained in the feedback thread. What I mean by that is if something's denied, people are going to wonder why it was denied, and while some people might usually assume that it was a small mistake that called for the denial, others might generally assume the opposite, which can potentially be damaging.
In general, though, the feedback shouldn't be seen as an embarrassment; feedback and constructive criticism are tools for us to use, and when they're public some friendly bystanders might give you a helping hand. The slightly ruder people who become rather judgmental about a roleplay being denied initially are going to be just as much so if they don't know the reasons, though I'm not sure if we have many, if any, people like that around here. There's probably a few in the bunch, statistically speaking.
And, if we're being honest, I do enjoy looking at the feedback thread and reading through what's been accepted/denied, including reasons for denial. It's certainly interesting to see some roleplays and usernames pop up that I've never seen around before nor ever see again, which isn't uncommon, lol.
So I'm definitely in favor of keeping the system the way it is. It's a difficult set of rules to abide by or anything.
