Well, I would rather be quiet instead to comment for something what you don't know talking about, obviously there are reasons for the inactivity in the Malware Hub, no need to guess nonsense like kids
Furthermore, everyone can play like professional Malware Hunters or Testers but that doesn't mean ALL of them does know how to avoid the risk ending up to be infected, keep in mind here are not only "advanced users" in the forum. For example, guests (non-registered) may does click the wrong link what someone shared here in public visible to everyone, so who to blame finally...
