IP address spam
I run a forum and have a problem with spammers attempting to join. We are a local forum and don't have any users that are more then about 200 miles away. I can block IP addresses individually but would like to do so in groups. example- a user tries to join from 123.123.123.123 and I reject because that address is from another country. The next day I get someone try from 123.123.456.456 If I block 123.123.* Is there any chance that could block local people?

Hi,

You did not mention the platform you’re using in your forum.
Anyway, I think this might be of help for you.

Stop Forum Spam

Besides this, there are some basic procedures that should be implemented:

– Always use the latest version;
– Implement a registration activation;
– Use difficult Captcha images

—————————————————–

If you’re using a decent router, you can always include an in-bound ACL that only allows certain IPs based on their IANA-provisioned IP addresses. Blocking IP from other registries and only allowing, say, ARIN-based IPs works great…
