I’m one of the user that created stake forum account for the sake of participating on the slot multiplier challenge that has good rewards before.
I’m done joining on such contest so I skip using the forum now because there’s no real discussion in there aside from the bonus submissions on the bonus thread.
Gambling discussion board here feels like home for active gamblers.
Me too, I was interested to join Stake's forum because of their challenges and giveaways and I was actively participating in the weekly slot challenge, but I stopped last year because the number of participants is increased a lot which makes the reward less than years ago

.
This year I still try to participate only in the weekend stream giveaway but I do not do it every week, when I remember only :0
Since I have won few times in this giveaway years ago, I think the chance for me to win it more is smaller than before as well as due to the fact that the number of participants is increased significantly.
I was not there for real discussion too but some time I made some post in the local board to interact with other gamblers from my country.
It's true that the number of participants is now greater, but the prize pool isn't as large as before. However, we can see how successful Stake is with such promotions. When there aren't many participants, it's difficult to win, especially now that the number of participants is increasing.
I myself rarely participate in contests like this anymore, and I haven't participated much in over half a year. I might participate in some, but I don't mean as many as I did a few years ago.
