I have this file with some with millions of lines, I should delete with bash all lines that contain more than three times the word "..Nessuna Risposta" for row.

For example: in this output I should delete rows "1003", "1084" and "1096" (and then remove blank line) but not last row "1119" because this line contains word "..Nessuna Risposta" only two times.

I have find and tried this script, but the count *{3,} not work, because this delete all lines contains word "..Nessuna Risposta". Can you help me, please?
