panscient used to come from 38.99.nn.nn (a range I had blocked a long time ago) today it's coming from its own range
NetRange: 205.251.121.0 - 205.251.121.255
CIDR: 205.251.121.0/24
and has this simple UA : panscient.com
took robots.txt (where I don't have it listed) and moved on to the index page where it was stopped by my system.
I shall now block its IP range ;)
