How to get rid of spammers in phpLD

I own two "paid only" phpld directories and every week I find a lot of unwanted, non solicited links submitted despite of strong captcha options.
Could anyone have any recipes to get rid of robot submitters.

Your help will be much appreciated.

 

Try heavy or extreme distortion in image verification.

 

Find An0n and see if he is willing to take on the project. If you want it done, he can make it happen.

 

I noticed that even strong captcha is not enough to filter those bot submitters and spammers. There was a time I've seen a different kind of captcha that is equivalent to solving puzzles before you can submit and this will be more effective compared to standard captcha only.

 

delete from pld_link where payed<=0

 

very good idea, I will give it a try and see.
thanks v much. I appreciate it.

 

You mean from phpmyadmin?? or from dir admin.
I do it often from phpmyadmin and it works but then after a week or two, it's again the same story.

thanks anyway.
good day!

 

Captcha and Charge.

 

Heavy or extreme image distortion may mean real people cannot read it so you could lose sales that way. I'd look at alternatives myself.

 

try to use questions like "capital of paris?"... bots wouldn't know the answer but I don't do directories so don't know if you have that option.

 

capital of paris:??????????? even human cant solve this type of que.

 

Dude, read bloody thread before posting... That's what he wants, he wants ONLY humans to submit to his directory.

PS: some people still wouldn't know an answer to such a simple question but bots definitely wouldn't know.
