Attention WordPress Users
We have become aware of a module for WordPress that is abusing what we provide here, for free.
The "AVH First Defense Against Spam" (versions 2.2 and below) plugin is the sole abuser of this website in checking every connection before any content is served.
This website is here to provide access to IP/username and email information for when users register or post messages/comments and NOT as a general IP firewall.
If you use this module and your blog starts to appear in our daily top 20 API users, then you can expect to find your host banned. This will slow your blog and webserver down as it attempts to connect to the API.
You have been warned !!!
