Michael, thank you very much for your reply.
I took some time to look into this as well and I felt that there is no clear definition as to what an advertisement can be. It's seems to be a widely used label for anything a user doesn't like to see. I did refer to the definition of
advertising on Dictionary.Reference.com and found that
for the most part almost every definition refers to an advertisement being paid, offering a reward or having something to do with money.
As a webmaster, I would love to see some sort of standard where there is a clear definition of what is advertising and what is not advertising. I'm very willing to work with people to help resolve such issues as I personally do not see how linking to other websites is advertising; especially when referring to the very definition of advertising being that there is money or profit gained. Seeing as there are no referral links in the links going to other websites (or basically there is no way to track clicks, etc like Google does with their Google ads) I would not see that as a reason to block said links. To me a referral link that renders profit would say Site A referred this user to Site B, pay/reward Site A with x amount of dollars/cents.
Don't get me wrong, I find Google ads and all sorts of advertisements annoying. But I honestly don't mind Affiliate/Recommended links. Simply saying on a website, "I recommend these sites" is more of a "Hey, check these out" than any type of advertising. I mean, if we block sites that say "Check this site out" it can hurt users as they may not learn of other websites that they could be interested in.
I hope I've made some sense, as this can definitely be confusing. I admit, I feel a bit confused with all of this.
