I know you guys are trying to be all nice and fairminded and polite and everything, but I'm afraid I have harsher attitudes about both the spam and the browser compatibility.
Companies always TAKE the right to use, abuse, measure, and monitor us. It's a matter of class interests, perspective, and morality. If they really meant all that privacy jazz, they'd actually go out of their way to NOT record any personal info. A real anti-spam policy would mean implementing an SG system at the ISP. It would mean NEVER even having something to opt-in to. Look at the SG website - it's free and they never contact their users at all. An ISP is getting PAID, for cripe's sake.
If they'd get all the useless scripting out of their webpages, there wouldn't be a problem with different browsers. Users wouldn't have to expose themselves [turning their scripting on] just to use such sites. Anything fancy that they really need to do can be accomplished with server-side scripting. Most of it is garbage. Just look at the blocks of code programs like Dreamweaver stuff into every page.
If they say it's too much to do, I say they're big, they have the resources.
All the webmail sites suffer from the same abuse of scripting. I have to engage it to view their site, so they have to screen my webmail to avoid giving me a script virus. If I could keep my scripting off, the webmail site wouldn't have to do anything to protect me, I'd already be invulnerable. They make me prefer SMTP.
By the way, hows about a separate forum for this topic alone - SITES THAT SPAM or something?
