There's a difference between passion and idiocy. I think the main point here is that y'all need to hit the brakes and chill
Its a fine line between passion and obsession. Regardless, anyone that enjoys works of fiction and follows their stories with any level of interest, will be mad if you spoil the ending or some plot point.
And like I said before, he wasn't banned for spoiling Fallout 4. He was banned for being an idiot that was trying to invoke the rest of us to get angry at him. So the main point is, don't be an idiot and treat people how you'd like to be treated.
I got the ending spoiled for me by a thread on 8chan, and I just shrugged it off. I took it like an adult, I didn't throw a conniption fit over it.
1. You clearly don't care much about Fallout 4's story. That's fine, you don't have to. Others do though.
2. I don't recall anyone throwing a "conniption fit" over it. There was a strong negative response towards Harm, as there should have been, since Harm decided that trolling the thread would be worth his account.
