The option to automatically decline guild invites doesn't block the whispers which can be just as annoying, particularly when you're in a raid/bg. I just set a DND message to autorespond with my opinions of them, and reply with an apology on the rare occasions it's not some guild spam crap.
I'd be very happy to see it blocked if possible, the kinds of guild that use it aren't worth joining anyway so it would be no loss :)

There's a guild perk called Cash Flow that automatically adds gold equal to 10% of whatever guild members loot straight to the guild bank. The bigger the guild with the more active members, the more money for the guild bank (and usually straight into the pocket of the GM). Some people see that as a fair trade-off for accessing other guild perks, such as increased XP while leveling.
Some guilds also offer gold to their members for recruiting people, so the same lousy guild has half a dozen people spamming you to join, whether it's with the addon or not.
I look forward to getting an invite based on my contributions as a team mate, rather than just because I'm logged on :)
