Edge has summed up this topic pretty well, so props to him for being a voice of reason here.
While I feel this particular rule should be left vague, intent behind things is important. You were bringing attention to someone who, in a "competitive" setting was purposefully losing games. It was clear that he had multiple accounts that had more than 30 losses, and as soon as he won a single game he stopped using that account. I have joined a few games, and been keeping track of "Charnel."
Let's look at this for a moment:
User prior to Amnon saying he would be keeping track of the user had a score of 0-33, something EXTREMELY difficult to pull off without intentions.
Case after Amnon says he would be keeping track: User is now 1-33, and warned by a moderator, here is the game in question.
https://entgaming.net/findstats.php?id=11259956He proceeds to lose 4 more games in a row... but here's the interesting bit. Starting with this game, #56 - He begins playing better miraculously. Suddenly he's not losing every single game anymore.
https://entgaming.net/findstats.php?id=11263418Note the time he starts winning also lines up slightly with Amnon warning him? A bit strange. The only games he has lost since were when he was playing a 3v4, or was against a team that was relatively stacked in context. Also note Persephone (the account believed to be the same user) has not played a single game since getting his first win.
Back on topic: The issue here is not the rule being left vague. It's left vague as defining what "abuse" of the feature is can be difficult not only from a moderation perspective, but from an implementation perspective. ENT has no possible way of detecting how the game is going until it is over, and cannot track whether a team is actually winning or losing. Therefor; it is left to the moderator to review any case in which abuse of the feature comes up. I suggested a while back adding a similar feature to Island Defense but there isn't a way for the bot to recognize what player is on what team over there for !drawing. They actually need to go and design it to implement it.
viewtopic.php?f=279&p=505831#p505831So, the question remains. Is it considered abuse, when used in agreement with the entire team, to bring attention to a known game ruiner, who very clearly was doing it intentionally? Was Amnon right in his judgement? As per rules, he was. But given the whole context, probably not.
Sorry for the long post, but I wanted to bring those things forward as well as give a bit more insight into the rule and how it's handled.
