I took their automated "advice" many years ago when they first started the 3 ad blocks per page emails, and the income dropped dramatically. After a month with no recover, off they went. If a page is full of text, I use 2, otherwise 1 has been best. I don't want a spammy looking site, I want a useful one. So I ignore the "advice".
