Simple Block does what it says really. It’s effectively a software firewall of sorts. Enter an IP Address (or an IP range) or a host or a browser summary into the block rules table and save it. Then watch as visitors that match those entries are bounced and cannot access your site.
Block Rules: 
IP address is an exact match. 
IP range is an exact match to the specified range. 
Host is a like match, so if you enter for example google, anything that has google in the host anywhere will be blocked. 
Browser summary works just like Host. Add in a value like spider and any hit on your website that contains spider in the browser summary anywhere will be blocked.
In the settings page enter a bounce address of your chosing which will be used to “forward” the users on to if they match a record in the block table.
Filter Rules: 
There is also a filter table which is read before the bounce address. Values in this allow hits from users that match in exactly the same way as the block table. Because this is queried before the block table any matches will be allowed through.
Block Records: 
Is a list of all hits that have been bounced and also a single reason why. for example if you have a block record for browser summary – bot – and the google bot arrives on your site, you will get a record that the google bot has been bounced. (I don’t recommend blocking the google bot)
Also: 
Auto block is not (coded) enabled yet. Work in progress.
** Please note that this plugin has the ability to block you if misused! Please be very careful when using this plugin. This plugin requires database rights to create tables and also create and run a stored procedure. Without those database rights this plugin will not be able to function. **

CNHK SYSTEMS

The plugin keeps record in UNIX timstamp format of the last time each logged in user visits the site. Record for each user is directly 
visible on the users list table in the admin panel. The plugin also provides some utility function and hook.
<h4>Function Description</h4>
<code>user_last_visit( $user_id = "current", $verbose = TRUE );</code>
<ul>
<li>
Parameters :
<ul>
<li>mixed <code>$user_id</code>, the user ID or “current” for the current user (logged in user). default: “current”.</li>
<li>bool <code>$verbose</code>, if <code>TRUE</code> the result returned is a literal expression of the last visit time. default: <code>TRUE</code>. </li>
</ul>
</li>
<li>
Returned value :
</li>
</ul>
If <code>$verbose</code> is <code>TRUE</code> a string is returned. If <code>$verbose</code> is <code>FALSE</code> the UNIX timestamp of last visit is returned. When the user is not logged in, or when there is no record yet, the function return <code>FALSE</code> if <code>$verbose</code> is set to <code>FALSE</code>, a string if <code>$verbose</code> is <code>TRUE</code>.
<h4>Filter Hook</h4>
<code>"ulv-can-record"</code> : located in <code>"./includes/user-last-visit.class.php"</code> around line #24
Some users or some pages can be excluded for last visit recording. There is an admin page for that. But you can also add some additional filtering via this hook. This filter hook is applied within a <code>wp_loaded</code> action. So you must attach your functions before that (typically on <code>init</code>, once the user is authenticated). 
You can eventually use the <code>User_Last_Visit</code> class separately in your theme/plugin.
