The spam has gotten so bad on my blog that I’m now forced to start blocking a huge range of addresses. What is irritating is that spam never actually makes it to the point where people read it (or spammers benefit) but I do have a great deal to clean up.
I did some research and much of my spam is coming from Chicago via a company called FDC Servers.net. Here is the WHOIS record:
OrgName: FDC Servers.net, LLC OrgID: FDCSE Address: 141 West Jackson Blvd, Suite 1135 City: Chicago StateProv: IL PostalCode: 60604 Country: US ReferralServer: rwhois://rwhois.fdcservers.net:4321 NetRange: 67.159.0.0 - 67.159.63.255 CIDR: 67.159.0.0/18 NetName: FDCSERVERS NetHandle: NET-67-159-0-0-1 Parent: NET-67-0-0-0-0 NetType: Direct Allocation NameServer: NS3.FDCSERVERS.NET NameServer: NS4.FDCSERVERS.NET Comment: RegDate: 2004-10-12 Updated: 2006-12-27 OrgAbuseHandle: ABUSE438-ARIN OrgAbuseName: ABUSE department OrgAbusePhone: +1-312-913-9304 OrgAbuseEmail: *****@fdcservers.net OrgNOCHandle: NOC1402-ARIN OrgNOCName: Network Operations Center OrgNOCPhone: +1-312-913-9304 OrgNOCEmail: *******@fdcservers.net OrgTechHandle: PKR5-ARIN OrgTechName: Kral, Petr OrgTechPhone: +1-630-729-0228 OrgTechEmail: *****@fdcservers.net
If you’re in Chicago and can’t reach this blog then I’m sorry but I waste too much time cleaning up your spam Chicago.
In case your curious how to block spammers to your blog, there is a file called .htaccess which resides in the web directory of your site. Editing this file with the following lines will block specific IP addresses:
order allow,deny
deny from 67.59.0.0 (this will block the entire 67.59.x.x range)
allow from all
That’s pretty much it. This will block everything coming in from those IPs and in my case, spam.
