Did Hashnest flee and rug pull on us?

The platform is online but I don't see any activity:
  They don't respond to tickets
  They don't do any announcements
  They stop the posting for everybody on Telegram Hashnest open to  public channel
  They don't post on bitcointalk
  They since 19 August stop buying the hashrates committed to compensate the end of contracts

Can someone please confirm if they flee?
