Spam in Links Submit?

[AmethystCottage]

I searched the forums but can't find any posts about this issue.

I'm getting spam through my "submit a link." There are upwards of a dozen a day now; they have a fake email address, a one-line, badly worded complement of sorts about my site, and then a list of links to various places on some site that doesn't really exist.

I tried requiring a link back, but apparently it isn't *really* required, because they can put anything they want.

I've tried going to the "whois" to see if it's an IP I can block; they are coming from all over the world (including the US).

Can anyone help me find a way to deal with this problem? Is there a way to implement CAPTCHA with links submission?

I'm running v1.3.6.

Thanks for any help!
