Sounds like a good idea to me

I've been thinking of ways to counteract the spambots and I believe I've came up with something.

Basically, what I'm thinking of would be a 'Mark as Spam' link on the posts that would set a ban on the bots and flag them somewhere in the admin CP, and after 2 flags per post count of the user the user is automatically banned.

I haven't actually started coding it yet, but what I'm looking at adding is essentially another column on the member table that counts how many posts have been marked as spam, along with one function to pull the value of the table, check if it is greater than the post count * 2, and if so add an automatic ban against the username.

Another feature I was considering was a minimum post count to mark as spam, along with a button on the users profile for administrators to reset/change the spam count.

Also, since I haven't ran this past the admins yet, there's no guarantee it'll be used here, but I do intend on at least making it and posting it on SMFs mod site.

Sounds good. It definitively need a minimum post count, though. I say maybe 3 spam votes and the user is banned from posting and post marked as spam, in case someone registers to ban Juju, for example.

Also the questions when someone registers on the site should be changed to some that are more complex but still easy to answer by newbies. An example suggested on SMF site is stuff related to our site, like calcs, but it could maybe be something like "Type 'agaminmo' backwards | Écrivez 'agaminmo' à l'envers (Anti-spam)" followed by a question asking "What is our site name?" then "Type 5c4a3l2c without including the digits". I believe this could block more bots than if we just ask them to type Omnimaga in the field or to answer 2+2.

in any case, do NOT enable e-mail activation. You have no clue how much trouble I had to sign up on certain sites like United-TI and Ticalc.org that had it, because I never got the activation e-mail. Plus most bots are programmed for activation and in some cases, enabling it makes the situation even worse, spam-wise.

It doesn't work, apparently.

And the question is now set to write OMNIMAGA in lowercase.
