I just came across this on Tumblr and it's all true:

Dear fanfiction writers,

Please be aware that there are fake websites which have mirrored literally ALL FANFICS from Fanfiction.net. As far as I can tell, they are near-perfect mirrors, updating in real-time to FFN’s servers.

All of your stories, your profile, everything has been stolen and copied onto the following websites:

• www.thebuystock.org/
• www.talkfictions.com/
• fictionavenue.org/
• thanfiction.org/
  
• hmofiction.org/

They are making profit off your stories with advertisements. This is called spamdexing. Please report them. Theft of this hefty magnitude, literally millions of stories, should not go unpunished.

Also, do not attempt to log in to any site that looks like Fanfiction.net but is not. In theory, they could steal your email and password!

HOW TO REPORT

1. Go here: www.google.com/webmasters/tool…
2. Put in the name of the website (one report each)
3. Write in additional details: This is a spamdexing mirror site to www.fanfiction.net/ and has stolen my profiles and intellectual property.
4. Click “I am not a robot” and then “Report webspam”
   
5. Report more by clicking the link on: Go back to the webspam report form.
   

If you have anything on fanfiction.net, please report the living ******************* out of these websites.

Love you all <3

PS:  Make heads roll for this.
