How to block Seekport

Operated by SISTRIX. Seekport is an internet search engine. Originally founded in 2003, the search engine has been operated by SISTRIX, a platform intelligence provider from Bonn (Germany), since December 2014. The search engine is a public, free and independent alternative to Google. Seekport does not store user data and does not profile users. Seekport is also operated without advertising and has no conflicts of interest in the display of search results.

How it identifies itself

Mozilla/5.0 (compatible; SeekportBot; +https://bot.seekport.com)

robots.txt

What the agent asks to be told. It obeys this or it does not — nothing enforces it.

robots.txt
User-agent: Seekport
Disallow: /

nginx

In the server block, then reload.

nginx
# In the server block. 403 rather than 444: a closed connection tells the
# operator nothing, and an agent that gets a status code can log it.
if ($http_user_agent ~* "(Seekport|Seekport Crawler)") {
    return 403;
}

Apache

In .htaccess or the vhost.

Apache
BrowserMatchNoCase "Seekport" bad_bot
BrowserMatchNoCase "Seekport Crawler" bad_bot

<RequireAll>
    Require all granted
    Require not env bad_bot
</RequireAll>

WordPress

A child theme's functions.php, or a small plugin.

WordPress
// functions.php of a child theme, or a small plugin. Runs before WordPress
// builds the page, so a blocked agent costs one PHP process and no queries.
add_action('init', function () {
    $agent = $_SERVER['HTTP_USER_AGENT'] ?? '';

    foreach (['Seekport', 'Seekport Crawler'] as $needle) {
        if (stripos($agent, $needle) !== false) {
            status_header(403);
            exit('Blocked: Seekport');
        }
    }
});

robots.txt is a request. The rules below it are the wall.

Seekport publishes a token, so the directive above will work for as long as it keeps honouring it — and nothing except its own good manners makes it. The server rules match on a header the requester sets, which stops the agent that says who it is and not the one that copies somebody else's name. Botscope verifies identity against DNS and published address ranges, records which check decided each request, and shows you the ones that lied.
