No. I literally just received an email from wetsuit saying he has restricted the top 2 bonuses in each category from accounts that don't gamble. The botnets were using this to counteract the reduction in base reward.
That's strange, as I did gamble before. I'm receiving the message that I've to play on HILO/ buy lottery tickets.
I'm guessing it works like everything else on the site. That's a ratio of the total from free spins against total wagered. He will have set this at a very low threshold as he said he thought it would only affect the bots and very few people would notice it.
