I don't mean to ban anything. Well, maybe crass billboards like a huge one overlooking a bay not far from where I live, dominating the skyline.
No, I've never seen a Google or FB ad I wish hadn't been there. Sure, how aren't all ads like spam? It sounds to me like you're in advertising. At least, I've never heard someone who wasn't in advertising defend it, promote it, as you do - comparing it to trying to influence friends or loved ones (!), suggesting it's hard to differentiate from that...
Ok well, I'm happy for you that ads aren't a totally malignant presence in your life as they are for so many people, that you fear the absence of helpful ads etc. I eliminated TV, newspaper ads from my life a while ago, have never listened to radio with ads, so most of my days are ad-free. Although I don't get out much. Am no expert, I guess it's up to you to distinguish good from bad, but sure, defining lines between good and bad X isn't easy - and is continually changing, not to mention gamed - that's why we have judges, juries etc, and not computers deciding these things - because the spirit of the law is the important thing, not the letter of the law. Sorry I didn't put enough time into writing this.
