This spam issue needs to be addressed systematically, not by killing individual spam by hand. I’ve seen it on my own sites. Once a site is discovered by spammers, the site’s registration and post submission forms are added to some auto-register, auto-post software and spam just grows more and more by day. For starters, add a captcha to the registration and post submission forms.

Apparently, there was a discussion before I adopted SciScoop regarding such a captcha device but it involves quite a bit of work. If anyone has the skill and the time to create such a device for Scoop hosts, or if anyone knows where there is one available for free, please let me know. Otherwise, it’s going to have to remain manual deletion.

Thanks

Look in External Links for a good selection of open source captchas, then in Captcha Services.

Hi

It’s not a simple case of finding the right software, as far as I am aware, it has to be integrated into the Scoop hosting…

If there’s a Scoop box that can do it, then that’s a different matter, let me know if you spot one.

It’s also possible that the rather low rate of spam (as opposed to what we used to get!) before comments were limited to logged in users) is actually because the twisted farts are posting it manually, in which case Turing won’t help us out!

Thanks

Regarding veryfication if the spam was posted by automated tools. It can be checked if you have access to the Apache logs (access_log). Look at the User-agent and Referer fields in the spamer’s records. Also check if the spamer’s IP registered any other hits immediately before posting. If the poster did not load any images then it’s almost definitely a robot.
Regarding captcha. I am not sure about your hosting arrangements and how much control you have over the code. If you run your own copy of the Scoop, then adding captcha won’t take longer than a couple of hours. If you are running a shared copy then obviously you can’t do much.

Hi

I spoke with janra (the scoop expert over at scoophost) who verified that the dribble of recent spam comments are being placed manually rather than by a bot, which means a captcha isn’t going to stop them. So, I’ve re-enabled a href on comments and ask that Sciscoop regulars keep an eye out for spam comments I might miss.

Thanks again
