Anti-spam measures

Post by pavila » Tue Apr 26, 2011 11:59 am

This forum is protected by phpBB3 spam hammer. Here's how our simple anti-spam measures work.

These restrictions only apply to new users. They are removed automatically after your account meets certain criteria. Normal users will never be effected by these restrictions.

Spam poured in after our recent move to a phpBB forum. Captchas, registration questions, and other measures only stopped the stupidest scripts and annoyed everyone. Instead, we stopped spammers from getting what they want - new members can't post links. This method that has stopped 100% of spam so far, and it is totally transparent to most people.

How does it work?
New user accounts are slightly restricted to deny spammers a place to put a link.

These restrictions only apply to new users. They are removed automatically after your account meets certain criteria. Normal users will never be effected by these restrictions.

1. New users receive an error if they use off-site links in posts or signatures. New users can still link to dangerousprototypes.com, and a select set of white-list sites like Google Code, distributors, etc.
2. New users receive an error if they use certain forbidden words in posts or signatures. The error reports the trigger word to help you find and remove it.
3. New users receive an error if they enter non-English characters (like Cyrillic).
4. New users can't save a personal profile. Spammers like to put a URL in the personal profile.
5. Accounts that don't post within 24 hours of registration are automatically disabled and then purged. We get 100s of zombie spam registrations every day, an automated process cleans them out.

Who is a new user?
The above restrictions only apply to new users. We are constantly tweaking the definition of a new user to stop spam while not annoying real people. These restrictions currently apply to users who:

*Have less than 1 post
*Registered in the last 24 hours

The restrictions are automatically removed once an account meets these criteria.

Warning!! Extreme honey-pot mode in use!!
Users with 0 posts will be automatically deleted for certain common spam behaviors:

*Entering a profile
*Entering a signature with external links
*Entering more than 1 links in the first post

Help, I'm stuck
I apologize if you get caught in the filter. We'll keep tweaking it to find a good balance of usability.
