it is still on the site.
That’s what’s all about 
After I filled in my email address from the free gas popup :
Thank you for registering for the Jackpot Factory’s Free Gas for a Month.
We will draw the five lucky winners on November 5th,
so please be sure to mark this email as “safe” and stay tuned.

I think this :
a. is questionable why the email address can be filled in BEFORE the registration to the casino.
b. leads to more “type in” traffic to allslots.
A popup with good actions is nice but do not use this to harvest emailaddresses from players sent by affiliate sites.
Just remove the email subscription and let players know they can get the free gas tickets AFTER they registered.
Have not seen those anymore, which rewards casino has this still on their site ?
