The most important thing is when one or two ip involved in spamhouse it listed whole subnet as spam sending and try to put pressure on ip owner to justify the reason of spam which is not possible in every situation.
If it's an IP owner like ColoCrossing that A. is spammer friendly and B. has invalid SWIP info (see below) on many of its IPs then Spamhaus should ban all of their IPs permanently.
SBL on a /27 received yesterday:
http://www.spamhaus.org/sbl/query/SBL214228
SWIP info for that /27:
OrgName: Warfront Cafe LLC
OrgId: WCL-94
Address: 23 Walnut St
City: Wilkes-Barre
StateProv: PA
PostalCode: 18702
Country: US
RegDate: 2012-12-10
Updated: 2012-12-10
Ref:
http://whois.arin.net/rest/org/WCL-94
All of these ColoCrossing IP ranges also have invalid SWIP info that incorrectly lists Warfront Cafe LLC as the contact and Alex Vial has been aware for a few months that the contact info is incorrect since it was pointed out to him on the LET UGVPS/Crystal thread and he has stupidly chosen to do nothing about the incorrect info .
