This might be a captcha question, but it might not be...

Question 1)

Is there a DYNAMIC captcha solution, where it will automatically activate if someone is dropping links into the comments field, but won't activate if they aren't?

I don't want my real users to have to deal with Captcha.

But if someone writes a comment and they have a URL in that comment, I would like captcha to be activated.

I am assuming this is going to require javascript. I wonder if it is even possible.

Question 2:

In case that doesn't work out, could you just let me know what YOUR favorite captcha plugin is? The one that seems the most user friendly would be appreciated, because I don't want to discourage REAL people from submitting comments.

~~~~~~

Question 3:

If there was a way to automatically not accept comments with two or more URLs in them, that would be fine to. I would just put a note above the comments box not to post more than one URL in the comments area or your comment will automatically be rejected.

Question 4:

I have tried a couple of anti-spam plugins that say they require the user to have enabled either javascript, or BOTH cookies and javascript, in order to post a comment.

However, I still seem to be getting bot spam.

Is that because their plugin isn't very good? Or because they are using actual humans to post the spam? Or is it possibly because my theme is using some kind of non-standard code that doesn't work with the plugins?

On another topic...

anyone ever use conditional captcha?

It looks like if someone uses something that akismet thinks is spam, then they have to fill out a captcha form.

Looks interesting.

I have had success with the challenge question plugin. I manually create the questions that a bot couldn't figure out. Such as, "what sport uses a basket and an orange rubber ball?" I don't use math problems or common phrases.

I have yet to have bot spam from it. Had a couple people manually spam, but it's easy to clear those out quickly compared to the bots flooding comments with spam.
