I tell you what, since I've switched to manual member approval I've been getting 3-5 attempts everyday from people with .ru email addresses and/or registering names like cheap-vigra and win-casino! When someone registers a new account now, there is a message saying that accounts registered from certain countries will not be approved until the registrant emails to show a genuine interest etc etc. I've emailed a couple of suspect accounts but they didn't reply and therefore got zapped. The results are good though, since being picky about who is allowed in, there has been less spam.
