If we talk specifically about consequences now, then maybe you’re right and those messages never, ever, lead to anything “bad”. Or, maybe sometimes they do, and you just got lucky. Personally, i don’t know for sure.
But whichever it is, is not really important, even. The fact is, there are rules - specifically, the parts quoted and specifically highlighted in blue color in the post linked in my previous message, here. Those rules mean, “combat avoidance” is punishable by up to deletion of player account, at WT administration’s discretion - it’s right there, in the rules, in writing.
How often does it happen, or whether it ever happened at least once - is also not really important. Especially since some kinds of bans are private information, not to be revealed in public, as mentioned in this topic. The really important part - there is legal grounds for “banned for avoiding combat” in WT.
But please, also note how 1st post of this topic also speaks about majority of players seeing “inactivity” as a bad thing. Lots of players dislike when someone “runs away”, and their feeling is reinforced by mere presense of “inactivity” reason being present in the list of reportable offenses.
It’d be much better if instead of “inactivity”, that list would have “being AFK”. Simple change, which would perhaps create significant shift of whole player base’ view about what is, and what is not, reportable offense in the game.
And/or, maybe there is something else, possibly similarly simple, which could be done to improve most players’ understanding of what is, and is not, respectable in-game tactic and behaviour.
P.S. Heck, even game masters are not rock-solid clear about it, as discussion in this topic clearly demonstrated.
