using wpmu 2.9 and buddypress 1.1
this plugin has been helpful for the last month or two but about 1 day ago it stopped working. i don't know if i cam under attack by one spammer perhaps who has some way of getting around this plugin but i know it's not working since when i set it to 1px font size and noone should be able to know the random captcha string i still get lots of spam signups. by lots i mean i get one every few minutes. maybe they are reading the audio file - i don't know.
anyone else having this issue?
i think i have to drop this plugin and try something else.
