Well firstly, thanks for taking this to the forums so we can deal with this responsibly.
If you had checked /mctop axes any other time within the month, you would have seen that my axes level has in fact been steadily increasing. I have taken screenshots several times on a daily basis, and this can support my last statement. I'll post a link to the album of screenshots once they finish uploading to imgur.
It would be only human to assume that I had been cheating, since you noticed 500 levels appear seemingly without effort. Most of my time on the server recently has been spent training, particularly training axes, and anyone who visits mt mortar can support me with this.
You mentioned in your post a possible method for which I and the others you mentioned could have used to cheat - "using the party xp". This bug was removed several weeks ago with a revision of mcmmo. All subsequent matters related to this bug have been dealt with.
Again, I hope SOMETHING is done, or SOMEONE looks into SOMETHING.
Our admins read every post on every thread, and always take action when rules have been broken. It's disrespectful to think that they ignore what we say.
If you have any further queries I will be sure to address them as soon as possible.
