I am well aware that if you redirect a url to your localhost IP that you have effectively blocked access to that server, i.e...
127.0.0.1 a.tribalfusion.com
... will kill tribalfusion adds from that server. What happens if you do it the other way round? i.e...
ninemsn.imrworldwide.com localhost
... I can't find that documented where I've searched. Certainly switching the first entry around...
a.tribalfusion.com 127.0.0.1
... does not block the adds.
The reason I'm asking is that I am having a small war with the
Red Sherriff spyware firm. Eventually they told me I could deactivate their spy by closing off the servers in hosts, and they helpfully(?) gave me the following lines to add...
>>>
server-au.imrworldwide.com localhost
server-uk.imrworldwide.com localhost
server-dk.imrworldwide.com localhost
server-fi.imrworldwide.com localhost
server-us.imrworldwide.com localhost
server-nz.imrworldwide.com localhost
server-sg.imrworldwide.com localhost
server-se.imrworldwide.com localhost
server-no.imrworldwide.com localhost
server-pl.imrworldwide.com localhost
server-de.imrworldwide.com localhost
server-by.imrworldwide.com localhost
server-ee.imrworldwide.com localhost
server-lv.imrworldwide.com localhost
server-lt.imrworldwide.com localhost
server-ru.imrworldwide.com localhost
server-ua.imrworldwide.com localhost
server-jp.imrworldwide.com localhost
server-it.imrworldwide.com localhost
server-br.imrworldwide.com localhost

ninemsn.imrworldwide.com localhost

... will that work somehow or are they trying to pull a fast one. I don't trust spy firms.
