HTTP black lists stop comment spammers

Jun 4, 2008 by Paul White

I got sick of seeing failed viewstate in my event logs. so I wrote some code that checks visitors against a HTTP blacklist.  I found that one of my blacklists was full of false positives.  Not that the given IP wasn't abusive at one point in time but I found it was full of proxies of which are frequently used by legitimate users.  After comparing some user logs I found that I was blocking a few of my member.  The HTTP blacklist from Project Honey Pot works, but had the problem with proxies as I stated above.  However one that I have had much better luck with is the one by stopforumspam.com.
If you are looking to stop comment spammers from seeing your site, I highly recommend them.  Read on for a code snippet that shows how I implimented this block

For the longest time I had the wrong definition of what grey listing is.  Once I figured out what it really is, and implemented it on my server running SmarterMail 4.x. I saw a huge drop in spam.  If you hate spam, this might very well solve all your problems.  Read this article for information on how it works and why it works.

asp.net http module for project honey pot http IP blacklist

Mar 31, 2008 by Paul White

Project Honey Pot
If there is one things that developers agree on, its that hackers, and spammers should be hunted down, and Killed, ( I mean brought to justice ).  The guys over at Project Honey Pot are leading the fight against spam.  They have setup a HTTP Blacklist that developers can use to validate their visitors IP.  The only problem is writing some code to utilize it might be a little advanced for some.  I have created an HTTP Module for ASP.NET that will validated your visitors before they get into your site.  I even commented my code ( something I usually don't do ), so others can learn.  Give it a try and let me know what you think.

How to stop Real Player from downloading your videos with ASP.NET

Mar 11, 2008 by Paul White

Coming soon!!  Even though you can never block computer savy people from downloading your videos. The latest Real Player makes it so easy that even a computer handicaped person could download videos from your members sites.  After some hacking I figured out how to bock Real Player from stealing your videos.  All I am going to say is it involves an Http Handler, and an ISAPI entry to manage your .MPG extensions.  I should have a full write up on how to do this within a few days.
