I do not have the “report junk” option when I receive unwanted iMessages…. What is the best way for me to report these and to hopefully receive fewer. I am getting many unwanted text messages to groups of 20 people. Usually from an email address.

I am receiving many unwanted messages as text messages from unknown numbers or more often from unknown email addresses. These messages are typically sent to 20 numbers (of which one is mine). I always block the number or email address they are from but I get several a week from new email addresses. I always send it to AT&T via the spam report number (7726). The response is a request for the phone number. But the messages usually come from an email address. Please help!
