Applications have been rejected on numerous grounds, ranging from "too many" of that staff, to concerns about the behaviour of those people past or present that might stem too deep to be resolvable, to complaints received from other users about those people, to the application itself not demonstrating what is being looked for in staff (the application questions were designed to help detect whether people wanted the roles for the "right reasons" etc.).
There's a lot of possible reasons for being rejected, and I felt that to go in to detail on each would, in some cases, require me to get altogether too "personal" with people - and I speak from past experience here - doing so is not a good thing, regardless of how many people may claim that they won't be offended or really want to hear the reasons.
Therefore I decided that the most professional thing to do was to issue a blanket "Thank you for your application, much time was put in to the decision, but you have not been accepted" type message to all applicants who did not get the roles they applied for.
I will not be giving any specifics on rejection reasons to any individuals, in public or in private.
I hope you understand the position I have had to take in this matter, and the reasons why I took that decision.
Nothing personal is intended in any rejection - and that is why I have kept the rejections neutral, because I've been in plenty of situations in the past where people did take things like this personally, and old friends that I refused prior positions have fallen out with me or other players over it etc.
