I don't get why people are always saying 'but (official entity) didn't say it's wrong". It's pretty hard to enumerate everything that can possibly be wrong. Even the law, which is supposed to tell you everything that is wrong, cannot possibly write down every possible things you could possibly do that's against the law which is why there's a judicial system to fill in the rest. It's easy to see abusing the Duty Finder is certainly not something that'd add anything to the game. That said the detriment to the game is also very minor as the real effect it has is for some poor guy to hear the 'queue pop' sound 20 times before it actually happens. That said since it's pretty trivial to put in a fix that will greatly reduce this behavior (say, 30 second lockout after declining a Duty Finder), there's really no reason to not do it. I suppose one can argue there are more important things to fix, but since someone from SE actually responded to this, it's clear that for some reason this seems more worthy of attention than the 150 page thread on server lag, so they might as well fix it given we know this is one of the few issues they actually responded on.
