I had recently seen and answered a question about Silver Nitrate and werewolves/UV light and Vampires in Werewolf the Apocalypse/Vampire the Masquerade. I answered accordingly, but someone did answer using Werewolf the Forsaken/Vampire the Requiem. The rules difference couldn't be bigger unless you'd quote from the rules from The Werewolves of Millers Hollow. WoD and CoD1.0/CoD2.0 are in all regards totally different games with different backgrounds.
Now, I had around the same time asked a question about the Werewolf 20th Century Edition ruling on one topic, and yesterday someone answered with the correct ruling for revised. Yes, it is a correct answer for revised, but that was not what was asked for (W20 is the edition in question) and so is not only out of scope but what was written in the answer also was noted and quoted from the book in the OP.
So: What to do with an answer that, despite the game/edition been given in the question&tags, totally misses the point by quoting/referencing the wrong game/edition?
