Having the same problem with email addresses sending bad links (porn or whatever) to my iPhone tel# as well as 19 other phone#s as text. As the other users have stated, I blocked the email address, but, every new text from suspected same user has a different email address each time. I want the ability to block ANY email from sending me a text. Calling my carrier for each text received from this user would mean a call each day. The result of that call would NOT have a different result on new text because they're changing the email address each time. Just give me an option in messaging settings to BLOCK reception of text from ANY email address; I can live with that.
