From two long time and respected members of one of my forums with hundreds of posts each. Out of the dozens of IPs they've each used over the years, those are listed. I have no *recent* data, so it may have been a proxy at some point in the past they used.
I show nothing in my logs from either of those IPs from the last 60 days so its probably a safe bet to block the IPs.
