This is a marketing ploy - These are trick texts to get your money or steal your info. The scam works since it makes you think you are being talked about behind your back, and being a child of smart phones and scared of missing out, you fall for this scam. -- Do not respond to this junk. Forward and report as spam.
Friday and Saturday are the BIG nights for these scam texts, they are after a certain demographic, and if I got one of these, I would be insulted that scammers thought I was dumb enough to fall for this junk. The lesson? Play stupid games, win stupid prizes. You being played.
