Umseting - Portugisiskt brasiliskt-Grikskt - Sem identificação não haverá comunicação

Trata-se de racedo para pessoa que quer manter contato por email sem se identificar, apenas usando pseudônimo.

Note: This bothered me quite a bit. What you see is an exact translation. However, because of the note, I would rather go for a more "personal" message in Greek:
Εάν δεν μου αποκαλύψεις την ταυτότητά σου η επικοινωνία θα διακοπεί. (If you don't reveal your identity to me the communication will cease)
