They want to hack your Yahoo account.  Report to Yahoo abuse.

Yeah happen to me also, but my wife got the message she went nuts on me. Thanks to your responses save my day. This person new my name be careful don't text back. At first I thought some was playing a joke on me.

I too received the same identical text message from textgirl39 on Oct 15th.  Of course I did not add her but wow this is nutz that so many folks also are being harassed by the same number.

I just got a text from phone number:15186594713
They told me if I wanted to know who they are to add them on yahoo. There id is:  textgirly47
They even knew my name, but I don't know who this person is.

Dont add this person and block from your phone service immediately.. they track your GPS on your phone from where you text back. Luckily they texted my Google Voice number and not my actual cell number so they cant get a position on where i am.. but block them immediately. If you texted back.. you are screwed. Alert your cell provider and bank because they can gain access to credit cards by you texting back. Yes its THAT serious. Good Luck! PS: If you added them to Yahoo.... This is one of those things in life you would regret doing.

Crap, i just got the same one and sent a request to add them....hope a simple block does the trick!

I just got a text from this number, but they knew my name. I asked who it is and they haven't texted back yet.
