Is crewbux completely gone?

Tweet

I have been checking Crewbux for 3days now. Every time I check it, nothing appeared. I have almost $6 earnings with crewbux already. I will be upset if they're gone because I was very active viewing their ads since their minimum payout was $5 and they increased it to $10. Does anyone knew about what's happening with crewbux? Pleae tell me. Thank you!
