Who called from 9318967860

Inappropriate content. Lot of misspelled words.

Do not respond to unwanted texts or emails from questionable sources. Several mobile service providers will allow you to report unwanted spam texts by simply texting/forwarding it to 7726 (or “spam”) to enable the providers to prevent future unwanted texts from the specific sender.

(If your provider is ATT, try the code "block")

However, in many cases, the text origin, as seen on your phone, is faked.  The internet domain does not exist, or the phone number may have been spoofed.

this number texted my friends boyfriend saying lets let only latex stand between our love...  Why has this number not been disabled yet?!

You can disable it by forwarding it to 7726 (short code for SPAM). Your cell provider will investigate and block.

I received a text "I know what you want and I thhink I am ready., Text Back

Tarana-D" from that number... wtf. why do people waste time sending these irrelevant text messages?
