SpamHaus keeps track of abusive behavior originating from a large variety of gTLDs and TLDs.
SpamHaus calculates the abusive behavior of domain TLDs as the ratio of abusive domains that exist in a given TLD, to its total number of active domains.
In November, dot .Science topped the charts of the 10 most abused Top Level Domains.
For December, the crown is retained by dot .Science, with a Badness Index of 8.69 as 82.4% of all referenced domains are “bad.”
Second in line is dot .GDN and third is dot .Top.
Here is the full top 10 list for December 2016:
