Fight SPAM!

Home >>Random >>Fight SPAM!

This website has recently become a target of relentless spam attacks.
Some dumbasses (probably bots or worse Russian hackers) post unrelated messages and such. Possibly looking for exploits in the security system.

I pride my self in openness to any meaningful content and do not want to pre-moderate comments or make registration (with email verification) mandatory.
So I subscribed to https://www.abuseipdb.com free API service that checks user's IP address before allowing to post any comments.

If you by any chance are wrongfully denied access, just let me know and i will clear the block.

On my part i will ban and report spammers with extreme prejudice. Let's make internet spam free one IP at a time!

For webmasters here is plain PHP code i used to enable IP checking and reporting:

Code

<?php
function httpCheckAbuse($ip){
    $key="[secret API key]";
    $url = "https://www.abuseipdb.com/check/".$ip."/json";
    $ret=httpRequest($url,'GET',['key'=>$key,'days'=>60],$status);

    if ($status==200)
        return json_decode($ret);
    else
        return false;
}
function httpReportAbuse($ip,$comment){
    $key="[secret API key]";
    $url = "https://www.abuseipdb.com/report/json";

    $ret=httpRequest($url,'GET',
        [
            'key'=>$key,
            'category'=>10,
            'comment'=>$comment,
            'ip'=>$ip,
        ],$status);
    if ($status==200)
        return json_decode($ret);
    else
        return false;
}

function httpRequest($url,$method,$queryArray,&$status=null){
    $request = curl_init();
    // Set request options
    try{
        switch ($method){
            case 'POST':
                curl_setopt_array($request, array
                    (
                        CURLOPT_URL => $url,
                        CURLOPT_POST => true,
                        CURLOPT_POSTFIELDS => http_build_query($queryArray),
                    ));
                break;
            case 'GET':
            default:
                curl_setopt_array($request, array
                    (
                        CURLOPT_URL => $url."?".http_build_query($queryArray),
                    ));
        }

        curl_setopt($request,CURLOPT_RETURNTRANSFER , true);
        curl_setopt($request,CURLOPT_HEADER, false);
        // Execute request and get response and status code
        $response = curl_exec($request);
        $status = curl_getinfo($request, CURLINFO_HTTP_CODE);

        curl_close($request);
        if($status == 200)
            return $response;
    }catch (Exception $ex){
        return null;
    }
    return null;
}

Best Regards.
