Hello, Thank you all for your input about a network that did not provide an e-mail contact information. As Wout de Natris clearly pointed out, even Scania's telephone number was incorrect! So, to the ones who had recommended I call the network to report an abuse/spam, you cannot even trust the phone numbers provided. Either lack of abuse /spam reporting contact for networks has become more noticeable, as we find out that the contact channels provided are incorrect, or do not even exist. Here is another example. I tried to report a Spam that had come from IP address [204.116.102.91] which belongs to Spirit Telecom. Their Whois information shows the following: OrgName: Spirit Telecom OrgId: IAVE Address: 1500 Hampton Street City: Columbia StateProv: SC PostalCode: 29201 Country: US RegDate: 1993-07-01 Updated: 2011-12-01 Comment: FOR ABUSE Reports Please E-Mail noc@spirittelecom.com or Call, 888-864-7226 Comment: For Law Enforcement Agencies Subpoena Request and Info Please E-Mail customercare@spirittelecom.com or Call 800-686-7671 Ref: http://whois.arin.net/rest/org/IAVE ---- But after sending my report to noc@spirittelecom.com, I received this error message: Delivery has failed to these recipients or distribution lists: noc@spirittelecom.com The recipient's e-mail address was not found in the recipient's e-mail system. ---- Considering the time differences, and often language barrier, calling a network may not be possible. So, as strange as it may sound, networks need to provide a channel so that others could contact them and report network violations. Here, I have copied Spirit Telecom's other contacts so that they could know about this problem at their network. Thank you, Reza Farzan rezaf@mindspring.com
