Just to say that I have been running this plugin for about 3 days now and it has virtually stopped all spammers from coming onto my Elgg website, I have even been able to deactivate my captcha plugin.  I also see it creating a blacklist...

thanks, ive updated the bookmark :)

Use this plugin  http://github.com/elgg/emaildomains You will thank me for it when you want to upgrade Elgg: 

@federunix - I had the same issue, once i removed the hypeframework plugins the social login worked. Go through your plugin list and disable the 3rd party plugins one by one as it may be a conflicting plugin.
