Tumeni, I've already explained this before to you, personally, but I guess I'll do so again in the hope that it sticks this time.
The templates we use for warning PMs are predefined, and, yes, not particularly accurate. We don't see it as a priority to improve them, since the PMs are not a primary source of information. We always include a response in which the warning is explained.
As for the definition of spam - it is not exclusively flooding nor advertising. The definition of spam is unsolicited or unwanted electronic messaging. For an obvious example, if you go to the upper fora with a thread saying "HAHA ERF ROUND", you're spamming.
I'm sorry, but I don't see in those rules where spamming is defined or expressly forbidden.
Keep your trolling within its designated boards (CN/AR). Since you're already on three warnings, it's time for a short holiday. Let's go with 5 days for starters and see if that helps.
