I don't think this is the feature of a poorly-executed gathering, I think it's a feature of human-minds-given-some-threshold of people in a group you want to be part of deciding-to-do-a-thing, no matter what that thing is.

If you have above-average-ability-to-resist-social pressure, that doesn't determine whether or not you should have the sticker on. Or at least, the two factors at play are:

1) do you want to encourage people to ask you questions?

2) if the group is at the threshold, and you want to be asked questions, but you also don't want people feeling pressured to put the sticker on, then yeah, you might want to take it off, but only for the benefit of other people.
