Lots of spam in project comments

[dydx]

This is pretty intense!

3400+ spam posts

I'd suggest either disabling the anonymous comment feature, or at least adding a captcha system to it.

I can work on this a little tonight

Wow, thanks for noticing!

@luigi any thoughts? We can put a captcha on it

[luigi]

I think we should force a sign in to comment.

[dydx]

Yeah, that would really be the most straight forward solution.

A few years ago, I was deploying a captcha-less captcha which stopped > 99% of spam (assuming you don't get targeted). It had no impact on users and worked great. We could try that before limiting the functionality of the app.

Using a honeypot? I made this a while ago:

[sb8244]

Honey pots work, but this was a little different. It had a hidden element which started as value 0. When you click on the form (element button etc), it would change the value to a known value. The server then checks that this param is correct to know that a real click event happened.

It operates by knowing that most spam bots don't actually do things on the window, so focus events (which are window only events) won't fire.

Ah right, so the opposite of a honeypot (the spambot won't fill in the correct value). Makes sense.

Is this still a priority @luigi? A simple fix would be to remove the else statement here and add validation in the comments controller.

EDIT: I'll gladly submit a pull request for this...

[sb8244]

Hey @alex-hall . I submitted a PR awhile ago and manually cleaned the existing comments. I haven't checked, but I think it's taken care of. We still do want anonymous commenting

[sb8244]

It looks like there is still spam. This is possibly human submitted spam, which a honeypot or captcha wouldn't catch. It's significantly less than before though. Curious for @luigi thoughts here.

[alex-hall]

Thanks for the reply @sb8244.

Yeah there will always be some % of spam no matter what.
But taking a cursory glance at the comments, it's like 50:1 spam to legitimate anonymous comments.

If anonymous comments are absolutely required then a captcha solution really has to be implemented.

[sb8244]

I'd like to record the parameters passed up with comments to see what people are submitting parameter wise. There might be an edge case when JS is turned off with how this works. We can put a really simple honey pot for that, though.

The hidden captcha system should kill nearly all spam, unless there's a targeted attack. I believe scripting off is the most likely culprit, which is easily fixed.

[alex-hall]

Let me know if you find anything interesting with the params route, but I feel it's important to mention this issue has been open for more than a year now. It might be time to bite the bullet and implement a Captcha rather than spending time tweaking a honey pot solution.

Thanks for keeping up with this y'all. Let's just do a ReCAPTCHA. Quickest to implement and most popular.
