Yes. A lot of 'innovation' in marketing is just changing things to eliminate design decisions which are associated with scamminess and coming up with new ones which aren't yet overused by the worst bottom-feeders and so seem 'fresh'.
I know that there is a lot of art behind these type of patterns and getting people to sign up, etc. However whenever I see them discussing techniques, they seem to ignore the fact that people quickly learn to work around them.
If I go to a new company's site, I'll quickly try and figure out whether I can get the info I need without signing up to anything I don't want. I'm used to weighing up giving my personal details, signing up for emails etc. If your site seems too spammy, intentionally opaque, or just yechy, I'll just forget about it and move on.
Change the patterns or the KPIs, and I'm sure that many of your page visitors will change up too, especially the more savvy ones.
