Finally, I was there and using it when the website went down and this did not resemble an actual hack but technical issues. First there were a couple of hours where the website was up but no posts went through for anyone except occasionally when a new threat was bumped, mirroring the normal pattern of downtime issues that sometimes occur and then it just went down completely. This doesn't really resemble how a hack plays out but looks more like technical issues to me.
Even now, going to the front page, it loads for me, except very slowly and incompletely. This does not resemble a hack but technical issues.
