On Gamba a group can add its members by hand —name, age and photo— without them having an account. That is what lets a single person set up a group's profile. If someone added you without your permission, ask us to remove you from here: you don't need an account or to sign up.
What we need to find you
The name of the group (or a screenshot, which is fastest), the name you appear under there, which of the photos is you and a way to contact you. Without that we can't tell which profile we are talking about, and the photo stays published in the meantime.
What we do
We remove your photo and your details from the group. If the group keeps adding you back, or if the photos involve more people who didn't give permission, we take down the whole group profile: the Community Guidelines only allow adding people who are part of the group and who gave their consent.
Or write to us at info@joingamba.com from wherever you prefer.
If you have a Gamba account
You don't need to write to us: if you linked your account to that group, you can leave it yourself. Open the group from the Profile tab, tap Edit, and “Leave group” is at the bottom. You stop being listed among the members right away.
