Let me start by saying I've never done this, and never would. I view getting EXP in EQ as a side-effect. Just do the progression in every expansion and you'll be max/max before you're done. The devs have stated over and over that this is perfectly acceptable behavior. They're only going to be taking a very small number of mobs (the ones which auto-agro on them). Just get over it and do something else. On the other hand. Intentionally training someone is clearly against the rules and also just wrong. However you rationalize it, you're a jerk if you ever do it.
