    <content type="html">Yet again I spent almost full working day trying to improve antispam protection on wiki.openvz.org.&lt;br /&gt;&lt;br /&gt;Currently 99% of all spam on the web is &lt;a href="http://en.wikipedia.org/wiki/Link_spam#Link_spam" target="_blank" rel="nofollow"&gt;link spam&lt;/a&gt; -- bad guys are adding lots of links to the sites they promote in order to increase page rank values for that sites. In fact they get no profit from that, since in all recent mediawiki installation (including wikipedia itself) all the external links comes with &lt;tt&gt;ref="nofollow"&lt;/tt&gt; attribute. That attribute is respected by Google crawler and other such bots and basically means "ignore this link".&lt;br /&gt;&lt;br /&gt;Nevertheless spammers keep inserting trash into such wikis. Recently such activity mostly comes in a form of a user page (or user talk page) creation that looks like, well, a legitimate user page (something along the lines of "&lt;i&gt;My name is John Doe, I'm Java coder, my hobbies are swimming and fishing&lt;/i&gt;") but with a blatant plug added ("&lt;i&gt;Here are some cool sites: [&lt;u&gt;1&lt;/u&gt;] [&lt;u&gt;2&lt;/u&gt;] [&lt;u&gt;3&lt;/u&gt;] ...&lt;/i&gt;").&lt;br /&gt;&lt;br /&gt;For about 2 years or so wiki.openvz.org asks you to login/register in order to edit, so anonymous edits are not allowed. That helps a bit, but still there are bots that performs register, log in and post.&lt;br /&gt;&lt;br /&gt;So now I have added another restriction: users that have just registered can not create new pages. Here "just registered" means "registered less than 24 hours ago". Note that such users can still freely edit existing pages. Let's see if it helps.&lt;br /&gt;&lt;br /&gt;Oh, almost forgot to say it: looks like &lt;a href="http://en.wikipedia.org/wiki/CAPTCHA" target="_blank" rel="nofollow"&gt;captchas&lt;/a&gt; don't work at all! Either spammers have good OCR tools, or they hire enough human beings to "manually" decipher those cryptic images.</content>

    <content type="html">We have recently started a &lt;a href="http://wiki.openvz.org/Partners" target="_blank" rel="nofollow"&gt;Partners section&lt;/a&gt; on our &lt;a href="http://wiki.openvz.org/" target="_blank" rel="nofollow"&gt;wiki&lt;/a&gt; for those who are working together with the OpenVZ project in one way or another. Our intent is to build this over time to serve as a resource. And it already works -- a couple of companies have added their profiles recently.&lt;br /&gt;&lt;br /&gt;If you have created virtual appliances that use OpenVZ, or provide support services, or qualify in some other way, feel free to edit the page and add your profile there. If you have any questions, just go ahead and e-mail me, kir@openvz.org.&lt;br /&gt;&lt;br /&gt;Just a note that this section is quite different from the &lt;a href="http://wiki.openvz.org/2006_contributions" target="_blank" rel="nofollow"&gt;2006 Contributions&lt;/a&gt; section on the Wiki to acknowledge those people who contributed to the OpenVZ project last year.</content>
