Twiceler is broken. Today it went closed loop and made many queries per second agains front page of my site. Had to block IP. Even tried to call this company and mailed. NOTHING.

This Bot is identified as a search engine, when and where can or will the results be available for visitors? Is there anymore information on the type of search engine. I assumme it will be available to the general public?

They don’t obey robots. They don’t stop from hammering your site. They hit your site a zillion thousand times a day. They claim to be a search engine but where’s the page to search for something? BS. My site just went offline due to excess bandwidth due to this thing. I sent them an e-mail but I am honestly not expecting much.

If you don’t like this bot, block it with these lines at the top of your .htaccess file:
Options +FollowSymlinksRewriteEngine on
RewriteCond %{HTTP_USER_AGENT} twiceler
RewriteRule ^.*$ - [F]

Twiceler has to be the most retarded bot ever.
Instead of just blocking them (like the comment above), do a 301 redirect to their own site. Hopefully the bot is broken enough so that it will visit their own site instead.
RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} ^Mozilla/5(.*)Twiceler
RewriteRule . http://www.cuill.com/your_bot_sucks [R=301]

Their crawler is pure garbage. It’s crawling one of my sites with all kinds of garbage query strings and made up URL’s.
I’d say it’s more likely that it’s surfing for security holes.
They are obviously a bunch of flakes as they are just internet noise.

well this week i’ve been visited by that crap and i want to kick it out of our site…
but, i’m really new, and don’t know where to find this .htaccess file you mentioned before.

.htaccess files can only be used with Apache web servers. In most cases, the .htaccess file is placed in the top directory of the web site. Search for .htaccess in Google and you will find a lot of information.
