THANK YOU!!!!  It is irritating- someone has spammed 19 of us within the past 2 hours!  The path I have taken is when people respond, choose "Report Spam".   Unfortunately, there are only a few responded asking does anyone know who is in the group to request to stop/ remove.   I would like ot see a block feature- specific, unidentifiable numbers or all in the thread-- it should be with the cost we are paying for phone and the service.
