Spamhaus.org published today a list of the “10 Worst Top Level Domains”
The list is “not a list of the worst TLDs in quantity, several other TLDs have far more spam domains, but they also have vastly more non-spam domains. ”
“This list shows the ratio of domains seen by the systems at Spamhaus versus the domains our systems profile as spamming or being used for botnet or malware abuse.”
“This is also not a list that retains a long history, it is a one-month “snapshot” of our current view.”
“The TLDs listed on this page provide a needed service to spam gangs and in doing so are actually damaging the reputations of their domains and damaging the reputation of any legitimate non-spammers who have purchased a domain from them.
Although nearly all TLD registries (including the Country-Code TLDs, ccTLDs ) claim to be anti-spam, some seem to only factor the revenue made by selling as many domains as possible into corporate policy decisions. The use of these domains (in this case abuse) matters not to their calculations. Some TLD registries will claim it is not up to them, but to their sales-agents (registrars) to deal with any misuse, but if these registrars also do nothing, the problems remain.”
“A good number of the TLDs succeed in keeping spammers off their domains and work to maintain a positive anti-spam reputation. This shows that if they wish, TLD registries can “keep clean” by keeping the spammers and other abusers away.”
According to Spamhaus as of 05 March 2016 the TLDs with the worst reputations for spam operations are:
1 .download 75.9% bad domains
2 .review 74.4% bad domains
3 .diet 73.9% bad domains
