I want to be able to block all numbers from a specific area code. Very useful against spammers that use spoof numbers. I would also like to block all spammers from a specific internet domain, for example hotmail.com and blogspot.com. I am constantly receiving porn solicitations drop both of these domains, ie... rdfgrht@blogspot.com; sophiasfun@hotmail.com. I really love the Textra app, except for those issues.
