It's been about 2 months since I implemented my last anti-spam form submit code and surprisingly the spammers were stopped dead this time and don't seem to have a clue how to get around it.
Looking at my log today the spammers may have just given up on my site because the ton of failed posts no longer appears.
Here's a few highlights of the last anti-spam patch:
- Browser and user agent validation
- Data center blocking
- Behavior profiling
I think a few minor casualties are acceptable for my peace of mind and less work cleaning up spammers messes.
Bye bye spammers, nice know'n ya!
