like OP, online ads (partially) put food on my table. but that's where the similarities stop: whereas OP mentions he's "never been tempted to run ad-blocking software before," i've blocked ads for years. and i don't just block ads myself, i advise my friends and family to block them, too.

what most of my friends and family don't know is web ads represent, arguably, one of the most dangerous aspects of modern web UX. ad servers exploited with 0-day vulns are one thing, but what worry me (and what i despise) most are dodgy ads that try to mimic/replicate some aspect of the publisher's web UI, and ads that fraudulently misrepresent other websites (e.g. fake facebook notification ads). many of these ads run on the biggest networks.

so instead of repeatedly telling my grandma that the buttons on certain sites aren't actually buttons for those sites, or that the banner with the facebook friend request isn't actually from facebook, i just install adblock on her browser.

i'm well aware of the irony and the double-standard. but safety first, right?
