website security - blank forms

[kuau]

I was also getting an increasingly annoying number of blank form entries even though I had js validation on my forms. Then I discovered that most PDAs, BlackBerries, etc did not have javascript ... so much for my validation, but I do think it was from bots. Bots who got smarter. When the blanks were supplanted by really long drug spams I finally added a simple CAPTCHA I wrote myself and that was the end of it. Not one since.

I hate those illegible CAPTCHAs too, but mine is really easy to read so it was rather painless and sure saves me time by not having to clean junk out of the database.

Thanks for the help. I'm not getting any blank emails from users. Maybe it is blackberries/etc.

Is there a way around this without using captcha

There is a system called MathGuard that does something similar to Captcha but is a lot simpler, unless you can't add 2 numbers together.

Have a search for it and see what you think

I haven't seen MathGuard yet, which sounds interesting, but you can see the simple method I devised here...

Some forum members objected to the use of color, but I haven't had one complaint or one spam or blank since. Whatever works...

Thanks for all your help. I'll take a look
