So I'm having a serious text spam issue. Someone's email obviously got compromised and now it it texting everyone on there contacts in a large group text. There is no option to simply leave the group. You can't block the chat. So I individually blocked everyone in the chat but I cannot block the text messages coming from an email. Also the compromised texter keeps adding new numbers to the list so my phone is constantly receiving texts messages from either annoyed people or from the compromised email with a porn link. PLEASE HELP.
