I said who the f are you LOL, It auto replied thanks for message, configure numbers SMS URL to change this message. Reply HELP for help. Reply STOP to unsubscribe. Msg and Data rates may apply.

I replied Stop and it said that I successfully unsubscribed.  thanks

Got a message that Justin added me to his circle network. I looked it up and saw that it was a spammer so I told them to leave me alone and deleted the text. If I get another text I will try sending STOP.

Same as above. Received a txt saying I have been added to Keiths circle of friends. I didn't open it. Deleted. Stupid losers.
