Support is useless for blocking unknown texts

The info that you're providing for dealing with unknown texts is no help at all. The "Block phone numbers, contacts, and emails on your iPhone, iPad, or iPod touch" is no good because the #s spammers use to text me change constantly. Blocking them individually is dealing with problem after the fact.

And "Filter unknown senders" only segregates the unwanted messages. I still get notices they've come in and then have to got through the steps to delete/block them.

I'm getting multiple sex-oriented messages daily that I'm tired of dealing with. C'mon Apple engineers... you're smart people. Come up with a better solution!!
