I went into Dark Devices for the first time last week. I saw a lot of people killing these enemies and the progress bar wasn't rising. So what did I do? I made a shout:

"Why is the progress bar not going up?"
"We're farming exp! Only killing Lambs raises the progress bar, so don't kill them yet."

I wasn't in a party so my participation in the FATE didn't mean anything as I was getting no EXP. But did I go to the Lambs and kill them anyway? NO! Why? Because what right do I have to ruin everyone else's fun simply because I wasn't in a party or something? it wasn't my choice to make and it honestly would be a dick move to be some killjoy that pulled the plug on these people. What right did I have? Zero. The people who kill the Lambs despite people giving shouts not to do so are doing it for one thing:

These people kill Lambs for the sole purpose of ruining everyone else's experience because he/she believes he/she is more entitled than everyone else!

That's all it is. They may feel it's an exploit. they may feel it's not intended. They may feel whatever they may feel, but people who kill the Lambs and force everyone else to stop are the types of people who, quite frankly, feel that he/she has the right to determine how others should play. They feel like they are entitled with the power and authority to determine whether or not something should proceed in a certain way or not, and if anyone dares to question it, they are wrong.

This is similar to having a superiority complex, or even a minor form of God complex. In other words, they believe they are better than you and will determine wther or not you should have fun or not based on what THEY believe. Not you. Not the 100 people in the FATE. Not anyone but themselves. They feel they know what's best and will go out of their way to punish anyone who goes against them.

THAT is why people will blacklist them, and that is why I let everyone else enjoy the FATE the way they wanted to do it and even join in myself, because it is not my place to force anyone to play the game a certain way or not. The only people with that right are the game devs, and they will change it the way THEY see fit, if at all.

The OP and anyone supporting him, however, have no right. They only think they do, and that is what makes them blacklist targets for hundreds of people, and that is why this topic is a real mess.

After I post this, I'm almost certain I'll be replied to by the OP or someone who supports him about how I'm wrong or that I support an "exploit" or whatever BS they come up with, but it'll only prove my point that they feel like they are entitled to determine how someone should play the game, because they are control freaks who won't accept anyone who goes against what they think is right or wrong and will go out of their way to enforce it... all because they think it is their responsibility or right.
