I believe the fact that you are still here after 4 months means u have a trust in ur forum.
There is no reason to distrust a classic forum for Bitcoin community. The Razed team perhaps observed activities in the forum, saw good things and finally decided to take action with marketing via a signature campaign. It's truly good for their business because Bitcointalk has big community in Bitcoin users and cryptocurrency-accepted gambling industry. Additionally, it is good for forum community too with another paid campaign.
Another thing I like very much when I clicked on Sign Up to create an account, I saw that the Referral Code was automatically given to Bitcointalk.
It means you did not create your account by typing the razed.com link and start with it but in fact you click on
the given link in the graphic attached in OP. It has a referral code to Bitcointalk, as you can see
https://www.razed.com/signup/?raf=Bitcointalk
The team attached this link to follow up traffics from Bitcointalk forum members, who visit their platform by exposure in the forum and how many of them register accounts.
