Bots are flooding my site. I have tried various Captcha's but sooner or later the bots have figured out a way to break them.
My phpbb2 site is a bit special. It's actually a multi-forum hosting phpbb2 site, where users can sign up for their own hosted phpbb2 forum.
A problem with that is that I can not use many mods because most of them require that you also edit a template file and all the hosted forums have different templates set as standard. (And there's over 200 for the forum-creators to choose from)
Question is, is there any way to add an effective anti-bot mod, like for example a random question-mod instead of captcha (or preferably together with captcha) -WITHOUT- editing template files.
I know there are some mods where you don't have to edit template files, but I have tried them all and many bots slip through.
Here are two "random questions antibot mods" that may be effective but they require template editing.

If someone is willing to edit one of the above mods so it works without editing template files I'd appreciate it.
I could pay some for a good solution.. (via paypal)
