SpamHaus is a global keeper of domain and IP violations that maintains a list of abusive behavior originating from a large variety of gTLDs and TLDs.
Exactly how does SpamHaus measure that type of negative performance among domain extensions?
The abusive behavior “score” of domain TLDs is calculated as the ratio of abusive domains that exist in a given TLD, to its total number of active domains.
As of February 23, 2021, the top 3 TLDs with the worst reputations for spam operations are:
- .fail
- .viajes
- .exposed
At #5, dot .work is still high on the charts three years in a row!
Surprisingly, .tk has now dropped to spot #10.
