How it identifies itself

FedReporter Bot for FFIEC

robots.txt

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

robots.txt
User-agent: FedReporterDataBot
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 ~* "(FedReporterDataBot|FedReporter|FedReporter Bot for FFIEC)") {
    return 403;
}

Apache

In .htaccess or the vhost.

Apache
BrowserMatchNoCase "FedReporterDataBot" bad_bot
BrowserMatchNoCase "FedReporter" bad_bot
BrowserMatchNoCase "FedReporter Bot for FFIEC" bad_bot

<RequireAll>
    Require all granted
    Require not env bad_bot

    foreach (['FedReporterDataBot', 'FedReporter', 'FedReporter Bot for FFIEC'] as $needle) {

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

FedReporter Bot for FFIEC 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.
