Bot attacks

Post by Goemans »

My board is suffering from bot attacks. Every day we have to remove +- robots spamming the forum. What can we do about this, apart from approving every registration manually?
Thanks.

Stop them getting in in the first place.

Have a look at the topic just above where you posted

Kevin's suggestion is perfect, after reading the topic he linked, select the "Q&A Captcha" from the Spambot Countermeasures in the ACP -> General tab.
How to configure Q&A

ACP> Spambot countermeasures> Installed plugins> click the dropdown box and select Q&A (it will be greyed out)
Click the configure button then click add.
Add your question and answer (you need a Q&A for each language you have installed) click submit.
Click 'back to previous page' then click 'back'
Select Q&A from the dropdown box (again)
Click submit at the bottom of the page.
Done.
Also, I would suggest disable guest posting, make passwords have mixed case, numbers, characters, etc. & have the account activation by User, then authentication by email is mandatory for any chance to post a message. There are other measures you could take as well, but this is the best option. On one of my sites, I've just gone from 800-1500 spam per day to NIL, after upgrading the phpBB version.

Thanks for your reply.

I'm on phpbb 3.0.9, but I can't find the 'Spambot countermeasures' tab (I'm using the Dutch version, could this make any difference?)

Guest posting is already disabled. How do I make passwords have mixed case, numbers and characters?

ACP -> General -> Board COnfiguration -> User Registration settings.
-> Account Activation -> By User
-> Password Complexity -> choose 1 of the options

Not sure about why you can't see the Spambot Countermeasures tab.

It's not a tab itself, it's a link half way down the general tab menu.

Complicating passwords will not stop bots. A simple Q&A will.
