After getting down and running some tests I found that the spam drop coordinated properly can be used to give a major advantage to town.
So in other words TBF was originally right and it's not allowed.
(Because if town can remove the mysterious quickly enough, it's a whole lot easier to tell for fake results, and non-fake results can be used to find wolves pretty quickly after that.)
Of course, should you wish, you can share info with people you trust, but no thread splurging.
I know I just said it was allowed just before, but after research I have to contradict myself.
