I was using GSA to blast to a "test" site of mine. I was being a bit aggressive on the link building. Now when I look at AHREFS, my Domain Rank is Zero. Previously it was 42 or something. I don't have WMT installed on this domain, so I don't know if I got a penalty. I was wondering if anyone else has seen this happen. The URL rank is still good at 43. Could this potentially be a way to tell if we're being penalized by those of us not using WMT?
