Spam prevention in SMF?

[Kawaii-Volt32]

Hi,
Just wondering, what anti-spam mechanisms are included in SMF 2.0.11, and what extensions can I make to further prevent spammers/etc?

I'm referring to either bots or humans, whatever stops each.

If "link post prevention for new members" is a thing, can I exclude specific URLs like Google, YouTube, Facebook, Dailymotion and certain image hosts from being blocked to post by new users?

Thanks. I'm not new to forums, but am to SMF and have a great impression so far.

This page outlines a variety of options in relation to spam prevention: http://wiki.simplemachines.org/smf/Spam_-_my_forum_is_flooded_with_spam,_what_can_I_do

Thanks. I think the verification questions will work fairly well for the community, though I'd preferably like to see StopForumSpam implemented in 2.0.11, as a MOD, is there any news of an implementation for 2.1?

The CAPTCHA is fairly good too, compared to some others I have seen

SMF does not include any "mechanisms" to control Spam. It depends on your forum configuration... For example if you allow guests to post in topics, there are higher possibilities to be spammed than if you not allow them.

Some configurations related to this can be found in Admin > Configuration > Security and Moderation > Anti-Spam

As Kindred and others will tell you, the best defense against spammers is to not allow them to register is the first place (which obviously doesn't apply to guests as d3vcho mentioned). After reading the link Irisado gave you, take a look at this:

I actually made the security question for the site to be what my username is shortened (KV32): a huge hint is that the first 4 letters of the URL are actually KV32, which might throw a bot out, I assume they can't shorten things like 'Kawaii-Volt32'. I'm not sure if a real person would have difficulty, but I doubt it.

Thanks anyway also for the URLs and help too, hopefully my site won't be spammed too much (except by real people of course should they find the URL). Of course, guest posting is disabled to stop spam, I wouldn't allow guest posting anyway if I'm honest, it usually leads to other issues.

You need a minimum of 10 questions and should ask 2-3 ---  otherwise the human spammers will catalog the correct answer in short time and will get added to the bot database
