Stopping the phpBB spambots—for now
The Lucire forum has been beset by spammers since its relaunch, and to think that all it takes to defeat the ’bots is an extra question in the registration process. For phpBB users who feel that some of the advanced-Captcha solutions are too hard to implement, putting in an extra question, which must be answered correctly, seems to throw the spambots—for now. It’s apparently remarkably simple to stick in and the commenters at the below link have put in useful corrections.
