I am looking for suggestion on strategies / methods or links to good resources to thwart automated form submittals to our website.
We currently do a basic check for a validly formed email address and make all the fields mandatory. We disallow regexp. I don't think the end users will put up with one of those machine generated number/letter key thingys.

Any help is much appreciated. Thanks

Build one of the thingys where you have to enter the letters/numbers shown in the picture (I forget what they're called), they're faily basic to create and seem to do the job reasonably well.

I think you should have a look at this http://spampoison.com/ ,It`s not for form spam ,but it can also be used to give spam bots hard time.

U can insert some code for not allowing to post for example 20sec, so he can make post and wait 20 sec to do another one.
And for private messages same stuff but more then 20 sec like 120 or somethign
