How do you fight the automatic submission in your directories ?

the best ways is to use an image verification, also called captcha

 

Many auto / semi-auto submitters have managed to get past image captchas. reCaptcha and math questions are probably the next best thing.

 

I prefer the math questions, but I dunno if there is a mod(paid + free) for that for phpLD.
Why I prefer this one? because it keeps away the spammers and the retards

 

there are always some that make it through

 

Of course there is. e.g. http://www.directorydump.com/contact.php

hehe

 

If your directory is free, as ours is then automatic submission is no issue at all.
