Received the same text.

Called the number and got a message stating this is coming from a textplus.com number.  I emailed the company complaint address and CCed the FCC.  Sounds like textplus.com needs some way to prevent these abuses.

this is obviously a child molester im 13 and i got this same text to go on yahoo

Yep, same exact thing.  I actually responded because as it happens, I just got a new phone and thought it was someone I might know.  After finding this thread, I specifically told them that I was reporting them to FCC, and that any further attempts to contact me would be considered harassment and will be reported to the police.  I now have a record of the message and if there are any more problems, they get reported to the police.  Tell your kids to use that exact verbiage if you choose to have them reply.
