For past 4-5 months this blog and my contact form has been a target for spammers. From sites selling cheap Viagra to finding adult partners, i have been hit by all. Well, I was being lazy and didn't really fix problem but instead added these "keywords" to the banned list, but that didn't stop these guys! They just added a whitespace or misspelled the word, and were still able to spam there way through. Eventually today i went in added the ever famous image verification to the forms.
Now I know this isn't a silver bullet and it is possible to write a small image recognition program that can read these values and today's spammers getting pretty smart coz there is a lot of money in question. But i think to get this done it involves some cost (time and effort wise) and i believe that may not be woth it.
So on that note, Fingers crossed!!!
