I installed v0.9.6 many months ago on a subdomain of my business site, just as a prototype and to get my feet wet with the software. (I know security issues require update to v1+) Even though this site has never been published and there are only 5 legitimate test members, once in a while I get a streak of new members that seem to be bots. They might leave a URL with a .cz domain, or a link to some foxtv dot com. The only way I've found to keep these bogus registrations out is to completely shutdown new registrations. What can be done to improve that situation?
Note, I'm not really using the software anymore but hoping that when it matures a bit more I can take a fresh look. This is more for info and to help anyone else. Deleting the subdomain would solve my problem but that's not cool. :)
