I am currently running Gossamer Links 3.1.0 and I am getting an unbelievable amount of spam through my addalink form. I am looking for someone to install a plugin for me (custom or off the shelf) that prevents these bots from filling out this form. Whether it be a captcha or question/answer type product, I need something to stop the spam. It is overwhelming. Every week there are 1000's of bogus submissions that I go through and delete from the links admin page. If anyone has other advice on how to get rid of these spammers, please let me know. Thanks
