Oh, I wasn't expecting people to make the deduction I made.

There was a time when popups were considered malicious by nearly everyone (my mother would have seen this as suspicious during that time).

Thanks to popup blockers this feeling seems to be fading, and I see no reason whastoever to not cultivate it again.:

"Unless you are already logged in to a website you trust, any popup means that this website cannot be trusted. Contact someone you trust to check it if you really really need to use that site."
