Recieved unsolicited email wanting me to call this number.

I just did too.

Porn spammer.  They are harvesting email addresses from domain WHOIS data along with spidering computers they infect with a virus.  They then use AOL accounts to mass spam.

I got a text message from this number this morning......the email they used was qdsthor@aim.com.....it was just plain creepy

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.
