I filled in the form and was immediately met with a login form. No thanks and also made a mental note to never visit this site again.
There’s zero reason I should need to login to see these tips.
Also, you don't even know what kind of tips you are going to get. I kind of understand that the site wants my info for whatever selfish reasons, but it really fails to present what I'm getting in exchange.
Even if you don't fill the form and click on disabled button the log-in popup shows up. No thank you. I will not log-in to your website. Keep your tips to yourself.
