Reports spam if only ONE field matches with stopforumspam

[phred]

Thanks for this plugin, it's already cut down on our wiki spam!

This was dumping one me to the spam error page during login. The plugin requests this from StopForumSpam:
http://www.stopforumspam.com/api?username[]=Fred&email[]=fred.alger%40foxycart.com&ip[]=69.1.26.101&&unix

Which gives this response:

     <root>
          <success>1</success>
          <username>
               <value>Fred</value>
               <lastseen>1368463209</lastseen>
               <frequency>95</frequency>
               <appears>1</appears>
          </username>
          <email>
               <value>[email protected]</value>
               <frequency>0</frequency>
               <appears>0</appears>
          </email>
          <ip>
               <value>69.1.26.101</value>
               <frequency>0</frequency>
               <appears>0</appears>
          </ip>
     </root>

The issue is that "Fred" is a common spam account name. However, it's also a common firstname, my first name in fact 😄. My IP and email aren't used for spam, and I shouldn't be blocked from logging in (especially as site admin ❗)

I manually hacked my plugin to check if $isSfsSpam > 1 so that we can get back to work. Can do a pull request if you'd like.

You can use the whitelist setting to avoid being locked out. But I see your point....
