The problem with hubots (humans acting as spambots), is that they're always changing IP addresses and email addresses - so it's very difficult to make a preemptive ban on them.

Without having sendmail working, you can't have email confirmation and admin authorization. You might try adding Derek Barnstorm's anti-spam Question with niche specific questions. Also the x-post before links mod.
  

If you only have one solution to a problem you're not trying hard enough!

The fruit thing was working for a while, but now they've found their way past both the CAPTCHA and fruit.

I've set new registrations to Admin approval. I can still manage to authorise new registrations without sendmail working.

I don't approve the spam registrations and they still continue to signup.

Follow xnodyxx's advice for upping security and remember, if you don't approve them, then they are just annoying registrations and they aren't doing you any damage - aside from annoying you.

xnoddyx ... Thank you, I will try your advice but I hope these changes won't block legitimate members of registering.

Different email and IP addresses are used to register, so can the changes you suggested detect between a legitimate registration and a spam registration?

The harvester agent strings are already listed in The Guardian, unless there are some extra strings in your attachment that is not already on there.



Dandello ... Yes it can be annoying and time-consuming to go through the new registrations and delete the spam registrations.

I miss the days of having no restrictions in our forum when we allowed guest posting without requiring a membership. In large part, spammers ruined that freedom.

Our forum is truly worldwide, so participation pretty much comes from every part of the world. So particularly with us, there are times when people who want to register are unable to do so because of what amounts to our necessary, but nonetheless discriminatory anti-spam measures.

What's helped in our forum has been to include at the top of our required "User Agreement" the following message (obviously edited):

Note: If you have any problems registering in our forum, please contact Miss Emily
at MyEmail@MyDomain.com so that your registration can be activated. Thank you.


I actually highlighted the message above to make it stand out in our forum.

Ironically, with one of the two instances where our own forum's special message similar to the one above shows up in Google's search engine, an error message is presented because of our security settings. But that's actually okay since menu options in our forum also show up. No biggie.

***************************************

On a related note regarding anyone with a "sendmail" problem, even though I noticed this was implemented because of spammers, I've seen admins replace the standard "Register" tab with one of their own that explains in succinct detail how to register.

In other words, such a forum's "Register" tab links to a post in that forum explaining it all.

Pretty ingenious if you ask me. If there's a will, there's a way. Smiley

« Last Edit: Nov 14th, 2012 at 7:34pm by Bill Myers »  

Morning, noon, or night, have a great one!

Note: This forum doesn't allow for us to freely edit our posts or topics to make corrections as needed, so please remember to look for subsequent posts if you see any mistakes or outdated information. Sorry for the inconvenience.

Bill Myers ... I already have a similar message in the User Agreement area, but thank you for the advice.

Yes it's impossible with guest posting these days. Sometimes I visit other forums and I want to have an input but I couldn't be bothered going through the registration process so I end up leaving. Web surfers visiting my forum may be doing the same thing.


xnoddyx ... The new security settings doesn't appear to be working, still spam registrations. Maybe I'll try to increase the number of CAPTCHA and see if that helps.

Hi Miss Emily

Activate Referrer Security what this is for it is to stop Requests, Actions from outside your domain/url to YaBB this will not affect legitimate members

if you have the default 2.5AE harvester agent strings this list will add EC2LinkFinder to it.
Harvester Blocking this will not affect legitimate members see http://en.wikipedia.org/wiki/Web_scraping and http://en.wikipedia.org/wiki/Email_address_harvesting

Proxy Blocking ok why i say turn this on is that most of the hubots i have seen come from anonymous proxies you can have a look here
http://en.wikipedia.org/wiki/Proxy_server and decide if you do want this on or even test it for a couple of days just to see

Scripting Blocking this will not affect legitimate members.

I'm still getting the spam signups by following your instructions.

They are not registered because they need admin approval, but they are just an annoyance. I guess I have to put up with it.

you will still get spam signups as this will only help to curve some of them what you will see is in your error log as well as "You failed the fruit check!" you will also now see "Proxy Access to this forum is denied!"

Try adding the StopForumSpan mod. It checks against their database - downside, there are some IPs there that don't belong - upside, it does catch a lot of spammer IPs.

xnoddyx ... Thank you for your help. I see those messages in the error log, and also "Username / Password mismatch."

Dandello ... I think it should be okay for now. The spammers can keep registering but they can't get past Admin approval, so at the end of the day the forum is still free of spam.
