Ahh, yes. The age old debate. So long as you, their provider, doesn't
consider it abuse, they should be relatively safe. Obviously, there are some
net blocks up to stop the probes. There always are and always will be.
Networks don't like scans. One thing I'll say about NJABL, it's probably the
most accurate list for what it does. With the added proxy testing, they'll
get more people using the list, along with more complaints. I'll be adding
my log IP's to that list soon enough.
