The 406: Montana
Contact
Ask a person.
A question, something broken, an idea, or a problem with your account. This goes into the same support queue the app uses — you get a reference number back, and an answer by email.
Already signed in?
There is a support screen inside the app, under the gear icon on your profile. It keeps the whole conversation in one thread, and you get told when there is a reply.
Reporting a photograph or a person
Use the report button on the photograph, the comment or the profile. It sends the moderator the thing you are reporting alongside your reason, which this form cannot do.
Copyright
A takedown notice has to carry two sworn statements to be valid. The copyright form in the app collects them; a notice missing either does not start the clock.
Prefer email?
Write to the contact address instead. It reaches the same person; you just do not get a reference number back.
