Anti-Spam Options - Automatically deny registration for users with multi-dotted email address

On my forum many bots have multi-dotted email address so I wanted to avoid them to create a new account on my forum.

The way to do this is create a new plugin to recognize these multi-dotted email address provided at time of registration and delete them automatically.

Steps:

• Create a new plugin using hook userdata_start

• Use this code:

$this->validfields['email'][VF_CODE] = '
    $max_dots = 1;
    if ($retval = $dm->verify_useremail($data))
    {
        $parts = explode("@", $data);
        if (is_array($parts) && substr_count($parts[0], ".") > $max_dots)
        {
            $dm->error("bademail");
            $retval = false;
        }
    }
    return $retval;
';

It only checks the part before the '@', so set $max_dots to the number of dots you will allow (I think one dot in an email name probably isn't unusual, but that's up to you). Also, this uses the default 'bademail' phrase, but if you'd rather have a special error messages for "too many dots" you can create a phrase and use the varname in place of 'bademail'.

Special thanks to kh99 who provided this solution.

wish there was better ways to prevent spammers..

How can a bogus email register if you are using email verification? The email addy HAS to be good to get the verification email in the first place.

If the member was able to register with a bogus email but has not yet replied to the activation email, he might be able to post if the permissions for that group are not set correctly.

It doesn't make much sense to use email verification AND allow them to post before they verify. Might as well not even bother with email verification at that point.

[djbaxter]

Exactly. But when I first started using vBulletin, I found the sheer number of options a bit overwhelming and some of my settings in the early days didn't make a lot of sense either.

Additionally, if a forum has more than one Admin, sometimes things can get messed up that way - best to restrict the permissions of co-admins to avoid this.

IIRC, guests aren't allowed to posts in the default vb install settings. I have never understood why some of these sites allow guests to post. That causes more problems than anything when it comes to spammers.

[djbaxter]

I agree. But Guests are usergroup #1 by default. Users Awaiting Email Confirmation are usergroup #3. I don't recall what the defaults for usergroup 3 are.

Thanks for this. I used this plugin, but did

[pre]$dm->error("humanverify_image_wronganswer");[/pre]so that the spammers (hopefully!) don't catch on that I've blocked their email address and then change their tactics.

I have a lot of spam Bot registration with similar username typs with Caps lock after the first word in the username.

Example of spam username:
IKowalski
KMcClella
KDesmond

Please how can i deny registration with username with caps lock on forum registration.

First word can have Caps lock other word should be lower case.

Your assistance will be appreciated.
