ok so, I saw your original comment. In your original post, you state it was something along the lines of "refusing to report someone is hardly the same as helping them do it lol". I can confirm that this is almost identical if not identical to the message you posted. As you rightly stated, it does not break any rules of the server.
This is a continous problem on the server. I see many harmless posts removed. You could argue "A response today would be nice fella" was a mean comment, but I don't think it's a cause for great offense. It's a known thing that TheXnator can take a long time to reply to messages for further comment, if at all. I was banned for 2 days a while ago - the first thing I did was contact TheXnator. A few hours later, other members of the Lead Team agreed there was no problem but could not undo the ban until they could contact TheXnator properly about it. The ban was then removed an hour before it expired, 47 hours later, when I was asleep and the ban was already as good as over. A month later I still have NO reply from him as to WHY I was actually banned. Additionally, the attitude of "well I *was* going to reply, but now I won't" is incredibly childish and is not something a staff member of this server should do, let alone someone in TheXnator's position.
This user did not break any rules. His "disrespect" was mild at worst, and it took longer for the admin to be upset at the user and reject them than to actually give a clear explanation, the lack of which for this sort of action is a continuous pattern. I do not know who this Denis guy is and I think TheXnator is alright in spite of these annoyances, so I don't think I'm particularly biased. This seems like a pretty clear-cut case.
