Naming the vanillas as mere vanillas is an advantage to the Baddies..
They can out their roles, while being safe.
Similarly, a goodie too have more chance of being lynched this way.
If a person is getting lynched, and he outs himself as "I am a vanilla", he have more chances of being lynched, as compare to he saying, "I am John Smith" (John Smith being a unique goodie role)
So just wanna tell you that generalizing the vanillas goes in baddies favour.
