It does look like a coordinated attack.
I believe that Enjin would get through it though, as it seems that they haven't let down their replies.
Thanks for the clarification on all the above issues. Raises confidence and am looking forward to the crowdsale.
Yes, enjin has done a good job with responding to the questions thoroughly. I even noticed that a couple of times they went above and beyond and asked a user to join a hangouts group with the members who were supposedly fake workers. Hopefully this works out for the project creators and doners.
