Thank you to everyone who answered my questions on my other post, the answers were excellent although some of them a bit beyond me to impliment.

Having thought about form and comment spam in a different way over the past few days I have come up with some ways to try and combat this.

I'm not sure if any of these will help or not but here goes with the ideas I had.

Spammers want to populate your forms with fake email addresses and links to website etc.

What if you split the email address field into two, the first field for the email address up to but not including the "@" symbol, the second field for the part after this symbol.
You could always add an image of the "@" symbol in the middle of these two fields so not to confuse visitors.

Then you would need to check for the "@" symbol in these fields and reject the data if present, presumably if spambots fill these fields you would get two email addresses and the "@" symbol in both.

For the web addresses you could always write the www part before the form field or even have an image of this and then check if that is added to the field and reject the data also.

A problem could be autofill and programs like Roboform etc that will populate these fields, Is there a way to disable autofill on forms?
How would you impliment any of these if they are are worth adding?

Hope i've at least given you something to think about and I apologise in advance if it's a bit vague.
