Spammers.

Post by Shaun Brewer »

To anybody that can help.

I have searched the forums and can find very little regarding combating spammers and most appears to be for v2

I have my own phpBB board and I am also an admin on another. However we are having problems with spammers. A big thank you by the way to everyone involved with phpBB!

My board is 3.0.1 (I will be upgrading to 3.0.4 soon), and the other I am an admin on is 3.0.4 both are vanilla phpBB installs.

My board has few visitors/members so as well as signing up I insist on a separate email from new members requesting me to activate the account - they also need to mention the topic of the board in the email to help ensure they are real.

This works in so far as I do not get spammers on my site but unfortunately lots of people don't read the instructions and don't get activated.

The other site has more visitors/member so manual activation would be a pain.

Is the only solution to the spammer problem to monitor the members and deactiavte/delete doggy looking accounts? Monitor the posts and again delete the spam posts/accounts?

I am particularly concerened at the number of spam account that are set up and just sit there - can I expect a flood of spam at some point in the future unless the accounts are deleted. Some are obvious spam accounts but I am sure some are not so obvious.

Thanks in advance

Shaun

What CAPTCHA (Visual Confirmation) settings are you using?
GD CAPTCHA (the colour one) with some foreground and background noise enabled is still very secure.
With the addition of a custom field, you can stop any SPAMbots from registering on your board. See: Knowledge Base - Custom Profile Fields as an Anti-Spammer Tool

Thanks for the reply ric323,

I believe I have the settings fairly secure, I actually find it uncomfortable to visually identify the letters, but hopefully that is just me.

Worth noting in 3.0.3 we introduced a new setting which automatically puts users posts on the moderation queue if they have less than a definable number.

I think the visual captcha has been broken - I have spotted several spambot registrations over the past few days. None of them had posted yet but they bore all the hallmarks - such as using an IP that isn't allocated to a specific country (which in my experience usually means it's been spoofed), a name that looks machine-generated (random letters and numbers rather than a name), a hotmail/gmail account name that looks machine-generated, links to some spammy site etc.

So I have already implemented that new feature that you mentioned - a very welcome addition indeed! 8-)
I will also be reinstating the anti-bot question MOD.

But I do think it's worth reporting that the captcha has been broken. My settings are, I believe, the default ones: GD enabled, foreground noise disabled, background noise 25 on x-axis and y-axis. My board is bang up to date with 3.0.4.

See my settings above

This Includes 'GD CAPTCHA foreground noise' and I am fairly certain that it has been broken too, I have had spam accounts sign up.

For info I have also had complaints that the characters are too difficult for some people to read.

Anyway I have implemented a twist on the code idea from the suggestions above on my board. It was very quick to implement (<1 hour), I was pleasantly surprised. I believe this would force the spammers to seperately target each board?

Thanks again everyone.

Also the new feature to put new posts on a moderation queue are helpful indeed. Once I upgrade I will probably use that too, thanks again.

I will post again if I get spam problems but was confident enough to switch to account activation by user, fingers crossed.
