You are correct. It has not been hacked; it is being attacked.
You obviously know you are right, but I use multiple browsers and your pointing out it is on chrome is correct. I will add this: if, using chrome(vivaldi) I search on google for the title you give on your 1st post and click on the freerepublic result, I do get the red warning; however if I right click on that link to open the google link in a new tab it works just fine and shows the freerepublic page just fine. So, it looks like google is actually doing the redirect if you do a plain click on their result.
