If you are using Linux you can put the entire hosts file hack on one line:
203.28.246.210 8kun.top sys.8kun.top softserve.8kun.top
Don't know if it works with windows, etc.
Also if you add newsletter.8kun.top to the list you will see Jim's newsletter signup blurb at the bottom instead of an error message.
On the otherhand leaving that as an error may help spot when the DNS issues are clearing.
