Black list of IP address

Hello. Now there are many programs that operate on the same principle as the F-Secure freedom . When checking IP that give these programs when connecting to any server, you can see that they are listed in the black list ( spam database ). This means that these programs are used to send spam, DDos attacks, hacking @ and other illegal actions. At the moment none of the IP addresses that gives you F-Secure freedom not to spam, but it is not excluded that, most likely, there are people who use F-Secure freedom for illegal purposes, resulting in some IP can fall into the black list. Please tell me the company can prevent such illegal actions of users ( spam, DDos attacks and other), to prevent the ingress IP in the spam database? As we know, F-Secure freedom does not require registration, does not collect any personal data, and consequently, it will be impossible to block users who will use F-Secure Freedome for illegal purposes.

    Freedome is an Internet access service for a rather wide audience, with a free trial. Given the large amount of users, there will be a few clients taking part in DDOS attacks, network scanning or spamming attempts. Just like in the customer base of any large Internet Service Provider. Most of these naturally come from users having computers or mobile devices infected with malware, without the user's knowledge.


    Unfortunately it will be impossible to completely prevent blacklisting of our addresses. We do, however, have some technical measures in place to block abusive behavior (network scanning, DDOS, spamming). Some of them are common best practices enforced by most ISPs, such as blocking outgoing SMTP email on TCP port 25. Email sending can naturally be done on the standard authenticated SMTP Submission port, tcp/587. We also employ rate limiting and traffic pattern analysis, which can be done without storing user data. These measures should help in keeping our addresses out of blacklists.
