API Changes

[7c]

After 1 year of operation, we see a more clear picture of this niche. We see that some providers

• use random subdomains
• share domains or even hostnames across different providers

Our current data structure cannot capture these cases. We will first change how the API filters hostnames at is/fakedomain/$domain and is/fakeemail/$email endpoints to the domain level. We believe that we should be banning the domain itself instead of the domain:

We will soon consider any subdomain of a known fake domain as fake too. We parse domains based on 'Public Suffix List' and will use the library https://github.com/lupomontero/psl to determine what part is a domain. In PSL terminology, even though 'clouddns.asia' is the domain, it considers cr.clouddns.asia. as the domain because the clouddns.asia is a known entity of giving subdomains. We previously considered *@b.cr.clouddns.asia as fake domain but was not checking for *@other.cr.clpouddns.asia, soon we will consider *@*.cr.clouddns.asia as fake domain.

In the case of line.pm domain we will consider *@*.line.pm including *@line.pm as fake domain.
