They might have tried, or they might not have. The clues can be interpreted, stretched, and manipulated in many different ways, as the hundred mafia games have perfectly demonstrated. In the paradigm of a serial killer's usefulness to the town, where the mafia is intact and has all its abilities, I don't consider revealing a clue about a serial killer who will be eliminated by a regular Reaper kill to be a good town strategy. By being a member of the mafia and putting this idea out there, you not only create a precedent where everything this player says in the future can be ignored, citing their lack of cooperation, but you also draw town blocks onto them. And given the current state of the game, this serves as a good setup for a monster's ultimate ability, doesn't it? A well-meaning town member, eager to win, will decide to go and heal or protect the serial killer, and will run into the monster. And if they don't go, then you can go and kill the Reaper. It's a win-win situation. It's definitely more reliable than trying to link the clue to the Master. Or whoever else you have in mind?
My problem with you is that town roles just don't seem to fit you. Leaving aside all the sophistry, I'll ask you directly - who do you suggest we execute? Besides the Master. You are suggesting that he be executed, aren't you? Who else is on the list?
If the Shapeshifter's ultimate ability is directed at you, that will be a plus for the town, as the town role will not be blocked and will not be deprived of its vote. Revealing the serial killer now, when the negatives can almost go through, is a necessity. This is a deliberate confrontation aimed at protecting the town.
As I said before, I find Revan and Gumer suspicious. The first one simply comes, leaves a couple of posts, and leaves. The second one "reveals" himself, but doesn't provide any justification, and doesn't get a modkill for the reveal.
