How to keep spammers away

Post by Pat G »

Hi

I have browsed over the first few pages of this forum and I haven't seen a discussion on this subject but if it has been discussed before, I apologize and please direct me the topics in question.

I am an admin for a 2500+ members phpBB forum and we have a real problem with spammers. How can we keep them away ?

Our list of blocked IPs is getting so large that I think we may be blocking whole countries ! And spammers have access to hundreds of proxies that they can use to work their way around IP blocking.

I have tried to set registration activation to "administrator" but we have tens of new registrations each day and it's a lot of work, plus I hate to make legit new members wait for up to one or two days when I am away and can't get my mail.

Right now, I have set registration activation to "user" so a valid e-mail has to be provided. But it's too easy to get a valid yahoo, hotmail or other e-mail address so that does not offer any efficient protection.

Is there any efficient way to keep spammers away ? Wouldn't it be possible to get and block the MAC address of a PC ? I mean, most PCs have an Ethernet card with a unique MAC address, don't they ? And it would be almost full proof ! Just a idea.

Thanks.

Hmmm, i think you cant access ones MAC Address (God bless privacy), but is there a MOD which allows to set a Cookie when a banned user trys to log in? That way you could simply check if somebody has a "Banned" Cookie...

Let me know what you think?!

if you could block a mac address, it wouldn't matter...you can change that in certain ways....

Also, they could just delete the cookie.

maybe not ban, per se

Instead of banning you could write a mod (or request one) that checks the domain portion of the e-mail & if it's hotmail/yahoo then require admin activation, if not require user activation. What spam problem? People posting too much? People scanning & getting e-mails? If it's people posting too much, increase the time limit between posts.

That sounds like a good idea ! What spam problems you ask ? Usually trouble makers who find some weird pleasure in posting offensive material, usually pictures.

I put in place a policy of not accepting any "free" email accounts for registration and set to user registration so the email they use must be valid..and not free. I have ammassed a very large list of free emails and even created a little script to strip <option> tags from free email provider pages so I can ban the gazillion domains they offer as I find someone using a new found free email account.

The only trouble I have with spammers have been porn sites that use their real porn site domain name but usually don't post. They seem to only want to get listed on the membership or its a webbot doing the registration for them?

There is a MOD that has the special picture thing to stop BOT's signing up.
Also, have you tried (this might be a MOD, not sure) having the user, so he does not have the privilage to post piccies? Not sure if its a MOD or not.
