And what's this
You know exactly what it is but I'll clarify it for you: The default
CAPTCHAs. Do you see the jQuery one there? Or the Sortables one? Or the Crazy Maths one? etc. etc.
Then that cuts the spammer's work down. How many people do you suppose are going to go out and install new plug-ins? Most of the people who come to this site can't even get phpBB working on their own (or even installed, for that matter), let alone installing some new code. If people would and could
install a new plug-in or other code then they could have installed any number of the MODs which added new captchas and such to phpBB 2 and 3 which have been around for at least 1 to 2 years. I didn't see that happening, from my experience.
In addition, if the spammer bot or whomever has even made it so far as to be able to download a registration page and then a captcha image/code/whatever, then that's already too far, IMO.
From my own experience of wasting my time examining Apache access logs, I've been able to use heuristics-based methods to implement blocks against automated user agents. In addition, I've stopped bots who crawl for email addresses (and God knows what else) by blocking IP addresses who are downloading more than X number of pages per second. I've also discovered that removing all traces of the term 'phpbb' from my site, along with using robots.txt directives to stop search engines from spidering my forums also works wonders from warding off the spammers, harvesters, and skript kiddie idiots who are just out there searching for anything and everything with 'phpbb'.
I've solved the spam problem for myself, so I've gotten what I wanted. I know my solutions work, but I can't say the same for everyone else's problems.
