Not only wpmu, wordpress Standard also has the spam registation problem.. especially with buddypress.
@m@rk I know SI captcha work with buddypress. I created a test installation and tried, its works there.. but when i tried in another shared hosting package of same server, it doesn’t. I dont know the reason. The image is not get displayed….
I read that article. At the end of it, there is a suggestion for using Invisible-defender plugin modified for buddypress. I tried that plugin, but it shows error when a registered user try to login. The plugin available at wordpress plugin site is not for buddypress i think.. Anyway i installed the latest from wordpress plugin site. Let me wait and check whether it block spam registration.
I tried captcha technique. but some how its not working with my installation. I dont know what the exact reason is. The image is not get displayed. when i clicked on the test link at the Si Captcha settings page, it is redirected to “not found page” ..
But Buddypress test site (testbp.org) does not hold a captcha.. but still it seems that there is not much spam registration. How they control spams without using captcha. Any idea about it?..
User profile photo also has some problem… Its not possible to upload at the registration time… but when i tried to upload from profile… then its work fine….
