Could you list all those 132 icon sets somewhere - iconduck.com/sets returns 404 and in iconduck.com/licenses you are showing only 1-2 set for each license.
If you want, you can join the MailChimp so that I can let you know when that page is back up: https://iconduck.us7.list-manage.com/subscribe?u=66c12f50e51...
