I have a Moto G first gen and want to block someone who is texting me. Is there a way to do this?
in Messenger - Android Apps on Google Play has a block sender option (really just archives it but you never see it)
open up the message thread from the contact you want to block
tap the 3 vertical dot menu in the upper right
tap People & options
there will be a block option (with the number being block listed)
