Looks like this might have been a improper adult content or maybe a Malware attack:
[ad#cricket-right-ez]If people are wonder what NSFW means:
Not suitable/safe for work (NSFW), not work-suitable/safe (NWS), or not school-suitable (NSS) is Internet slang or shorthand. Typically, the NSFW tag is used in E-mail, movies (such as on Youtube) and on interactive discussion areas (such as internet forums, blogs and community websites) to mark URLs or hyperlinks which may be sexually explicit or include audio containing profanity, helping the reader avoid potentially objectionable content.

It looks like this was done with using Tinyurl and has been flagged for either Spam, Fraud, Malware, or Any other use that is illegal. I am glad Tinyurl did catch this and stop it. If you see something that say NSFW in your twitter account your best bet is to delete it and go on with your life. I am sure it is something your should not go to probably because it was a malicious way to get your to go to the link. If you want to preview the urls that are used by Tinyurl, just visit the preview feature. If anyone else hears of some kind of Twitter attempt let me know and I’ll blog about it. This would be the best time to install [intlink id=”2205″ type=”page”]Free Anti-virus and Free Firewalls[/intlink] to help prevent from getting Viruses or Malware.
