@r-a-y I have BP on several installs of WPMu (all latest versions) with the same results. http://terryhall.biz (root site) & http://wp4seo.com (secondary site) – the avatars are not active links but the user name has a link ~ http://geeky.terryhall.biz/author/mrcleam which is not pulling avatar from http://terryhall.biz/members/mrclean –
Comment avatars are working. This was not a problem in BP 1.2.3 ~ is the “bp_root_blog” a new feature? Seems to be related to capability….

@kiwipearls the only product I’ve fond effective (about 95%) is the antl-splogging @ http://wpmudev.org – it’s a premium membership site on he expensive side, but it’s working for me. (btw ~ i’ve used all the methods you listed above) – my thinking is that sploggers are hiring people to setup their blogs and answer captchas…

Upgraded from BP 1.2.3 to 1.2.4 (automotic upgrade) – my blogs directory is empty – “Sorry no blogs found) – Main menu blogs item.

Using WPMu 2.9.2 & default BP Theme. (I’ve removed all BP Related plugins & BP is only active plugin. Also deactivated/reactivated theme)
