I think it's disappointing (and could be argued as unethical) that YH is using traffic from cancelled and unregistered subdomains from other resellers websites to build their own brand http://www.hostinger.co.uk which is setup as a youhosting reseller itself.
In other words they are creating competition and channeling the traffic from other resellers to build their own reseller brand under the main brand.
To see for yourself, visit any fake / nonexisting subdomain from any of the major YH resellers such as
and many others..
The one exception I found was 1freehosting.com & serversfree.com, they are able redirect subdomains which I believe are both owned by Hostinger as well (i think?).
