How to block unusual bot, like "bot[\s_ :,\.\;\/\\-]" name?
<p>until today I was blocking unwanted bots in .htaccess</p>

<pre><code>SetEnvIfNoCase User-Agent .*mj12bot.* bad_bot
SetEnvIfNoCase User-Agent .*baiduspider.* bad_bot
</code></pre>

<p>But I noticed lastly that I have unusual bot making mess on my serwer but don't know how to block it because his name is:</p>

<pre><code>bot[\s_ :,\.\;\/\\-]
</code></pre>

<p>I will be grateful for any help</p>
