I guess he refers to the usage of redirection links such as:
http://www.brightshare.com/clickscounter.php?compaign=xxx&groupid=0&bTag=xxxxxxxxx_aff_&affid=xxxxxxxxx
and not using links directly pointing to the casino’s name like http://www.allslots.com/blablabalbala.
(Maybe they used links like this in the past, I don’t know I always used the links that redirects through brightshare.)
So I guess Brightshare can do this way the necessary redirecting in the background – even if the casino will be down because of the domain seizure, they can redirect you to another temporary domain and nothing will be lost…)
