ignorelist.comは安全ですか？

sounds dismissive and unfriendly, suggesting a site where people or things are neglected or avoided. It doesn't convey a positive or welcoming message, which could turn users away. The name itself seems unappealing and might make visitors hesitant to engage with the site.

ignorelist.com is a dynamic dns forwarding domain used at freedns.org. Using the name requires a "prefix" (aka subdomain), such as "flintridge.ignorelist.com" etc. Some user accounts likely have set up forwarders -- [some name].ignorelist.com to yucky spammy or phishing sites. It is the prefix name that matters, associated with some specific individual. The base domain name is legit and benign, public, and doesn't go anywhere unless you specify a prefix (aka subdomain). You can read more about how dynamic dns works at the freedns project.

ignorelist.com is perfectly safe. It is a DDNS service. Some of the subdomains are unsafe, and they should be rated individually as such. The subdomains have no affiliation with each other; the safety of xxx.ignorelist.com has nothing to do with the safety of yyy.ignorelist.com.

The domain ignorelist.com, registered through DOTSTER, INC. is listed on at least two SPAM blacklists as of today. This does not necessarily indicate that they are guilty of sending SPAM, merely that the server that their IP address is associated to was confirmed by at least 2 sources to be a gateway for SPAM. This leads us to recommend caution on this server as it is possible that if it is compromised for SPAM, other data could be compromised.
