With this plugin you can define a PCRE regular expression against which data entered 
in XProfile fields will be matched.
For example:
<ul>
<li>check webpage field for a correct(-ish) URL or domain name: <code>%^(https?://)?([^ :/]{1,63}\.)+[^ :/.]{2,63}%iu</code></li>
<li>check age field for a sane(-ish) value (0-199): <code>/^1?[0-9]?[0-9]$/</code></li>
<li>check phone field for a sane(-ish) value: <code>/^+?[0-9 -]{7,45}$/</code></li>
<li>check any field for a minimum and maksimum length: <code>/^.{10,100}$/u</code></li>
</ul>
You can also configure a message to show when a field data does not validate.

<li>Moderators can see the number of approved comments for each user.</li>

Nice

Great Plugin

Does the job

It's really good


There are many better ways to handle spam than this garbage. Indeed i with the false positive rate this plugin has it is worse than nothing


Worst antispam plugin


Akismet has been with me since I've been on WordPress and really doesn't miss when compared to other solutions. Keep up the great work!


Doesn't miss a shot


Works very well for basic users so they do not have to buy a paid one just to protect a small site.
