If you actually visit 301works.org you will notice that there are a whopping _seven_ URL shorteners that have uploaded any data at all in the past 6 months:
- rn.tl / lensrentals.com
- nbl.gs
- qr.cx
- tiny.cc
- urlcut.com
- url.ie
- va.mu
And to be honest, those 7 shorteners aren't exactly big fish in the URL shortener business.
