By mistake I'd created a whatsapp group , instead of a transmission list, and as a result had exposed people to each other, what I could not do.

As per my understanding, even though I'd deleted the group, right after the creation, everyone in such group have all the names.

Supposing that not everyone have yet accessed the names, is there a way I could revert this situation and "save part of my skin" ? At least with those people that had not yet accessed it.

Thank you,
Ricardo
