.sexy and .uno raise the average collisions list size

The third batch of new gTLD collisions lists has been released by ICANN, raising the average number of domains that registries are being told to block on extremely cautious security grounds.

The average number of second-level domains to be blocked per gTLD is now 1,904, largely due to the impact of very large lists for .uno (which has 8,187) and .sexy (6,560), which were published yesterday.

This number is only going to get bigger as more cool-sounding Latin-script gTLDs raise the average.

It will be tempered somewhat by the IDN gTLDs, however. The average list for IDNs has only 253 names on it, based on the five published so far.

The most popular strings, ranked by the number of gTLDs’ lists in which they show up (out of a possible 18), are:

www18
com16
org15
net14
casino13
isatap13
m13
wpad13
uk13
info13

There are 30,581 unique second-level strings in total, all of which are fully cross-referenced and searchable at DI PRO.

The most-blocked exact-match brands so far are Yahoo and Google, which both appear on 10 lists. Apple, Facebook and YouTube appear as exact matches on eight.
