‘Embed Link ShortCode’ tries to emulate the functionality that facebook has when a link is pasted to the input status. 
But it doesn’t happen when you paste a link in the body of a new post (as when you paste a youtube link in the visual view of a post), it’s done using a shortcode. 
The provided link to the shortcode is fetched to get the meta tags, and these meta tags are used to render the new post content. It tries to get an image and put it as 
post default thumbnail, and it uses some meta tags to get title text and to add a quote. The order in the post content is: image, quote and link. 
If you don’t like the HTML render, you can always edit the code to change format or suggest me some changes.
Usage:
1- Create a new post.
2- Add only the shortcode with the link (in HTML mode, not Visual) in the post body. For example:
[embedlink]http://example.com/example[/embedlink]
3- Push ‘Save Draft’.
If all is ok, the post content will be rewritten with the rendered html code. An image may be uploaded to the media library and added as post default thumbnail. 
 If nothing happens, click the preview link and some error message may be displayed. If a blank entry is showed, all is ok, then click Edit and you will see the rendered code. 
 Otherwise, it will be a bug: please, report it adding the URL you used and the plugin version (update to last version before report!).
4- Review the generated code.
<h3>Notes</h3>
<ol>
<li>The post format will be set to ‘link’ by default.</li>
<li>The image (if any is found) will be added to the media library and set to post default thumbnail.</li>
<li>The content post is rewritten when you save it.</li>
</ol>

This plugin automatically scatters invisible links to <a href="http://www.projecthoneypot.org/" rel="nofollow ugc">Project Honey Pot</a> spam traps 
throughout your wordpress blog to help catch and stop spammers.
Project Honey Pot is the first and only distributed system for identifying spammers and the spambots they use 
to scrape addresses from your website. Using the Project Honey Pot system you can install addresses that are 
custom-tagged to the time and IP address of a visitor to your site. If one of these addresses begins receiving 
email Project Honey Pot not only can tell that the messages are spam, but also the exact moment when the address 
was harvested and the IP address that gathered it.
Install this plugin to help contribute to the project and catch spammers by hiding links to honey pots (spam traps) 
in your blog. The links are never visible to human visitors, but the spambots and crawlers follow them straight into 
the traps.
Note: this plugin will not directly prevent spam on your site, but will help prevent spam for everyone by helping to catch the spammers.
If you also want to use the Project Honey Pot API to detect and block spammers from your site, try the <a href="https://wordpress.org/extend/plugins/httpbl/" rel="ugc">http:BL plugin</a>.
