You have lost it, you are defending the sending of unsolicited indecent photos to individuals who did not ask, nor want them. Both OP and OPs dad are in the wrong here.

Defending one person sending an indecent photos to an unwilling recipient is the same as defending them all.

Leave me alone.

Also I don't get spammed with spam emails, I have better controls around how and when I use my email address to avoid being on marketing lists et al.
