If you’re a blogger, particularly one who uses WordPress, you may well have received an email, or a contact form submission, with content very much like this:
You have been chosen by WordPress community to try out our new All in One SEO Pack Pro v2.1. For further information please click on the following link where you can also find the download link http://www.wordpresscommunity.net/all-in-one-seo-pack/
The sender’s email address will be a bunch of random letters at wordpress.org, something like firstname.lastname@example.org, and the sender name will be “WordPress Community“.
Do not follow the link!
This is nothing to do with WordPress or the All In One SEO Pack plugin, and there is no download link. It looks like some kind of a traffic-building scam, and you may be opening your computer up to a malware attack by visiting the site.
The plugin it refers to does exist*, but is developed and distributed by Semper Fi Web Design. As far as I can see, the wordpresscommunity.net domain has nothing to do with Semper Fi.
* However, I have no idea why anyone would pay for an SEO plugin when the free WordPress SEO by Yoast plugin is available.
