I posted the following on the Chiangmai forum in response to a comment but got no response! Does any one know if I am correct:

post was:

I was always taught never to use the unsubscribe button on junk/spam mail as all this does is confirm/add to his database that the address on the unsubscribe link is valid and he can then sell that address on as such and you get even more junk/spam mail!

Obviously it is OK to use the unsubscibe button on a legit site that you have used, but no longer want, as they have your address anyway.

I may be wrong but I am sure there is an IT guy around who can confirm or otherwise.

if you want to unsubscribe from a site e-mail. report it as spam.

that way you won't get spam from the site any more.plus it cuts down on junk mail

This is really harsh if you've opted-in.

Don't be lazy and think a spam report replaces following unsubscribe instructions for emails you legitimately receive.
