It hasnt been announced here yet, but Alex Pereira, new UFC middle weight champion, since November 13 is new Roobet ambassador. I wonder why Roobet keep silent about that

There is only a
tweet about that on Twitter, but not a single line on Roobet.com. I've searched in the news, but there was nothing about. I have only found some mentioned on promotions.roobet.com (
https://promotions.roobet.com/search?query=pereira), but the only available page is just a plain text (not very presentable for gamblers and fans imho).
Nope, I'm not sure when the exact date Alex Pereira become a brand ambassador on Roobet, but according to this tweet [1] there's a video where Pereira wear Roobet clothes on November 10. Roobet is very active to announce their new brand ambassador, huge win, promotion, giveaway on their Twitter. I think Roobet is very lucky to sign Pereira before he's now become a champion, because it would be costly.
