Apparent Google wave invite dupe scheme

So after i recieved my google wave invite i just happened to search the tag #googlewave on twitter to see what other people were saying about google wave. Surprisingly a major number of tweets went something like this :
"Just requested my Google Wave Invite! Get yours at http://www.google.com-wave.info - #googlewave #googlewaveinvite" Have a look at the image

Now this looked surprisingly fishy so i went to the site http://www.google.com-wave.info/ and found that apparently you give your twitter username and your gmail id to these people and then tweet the above mentioned tweet and you get your invite.
I dont know about you guys but this looks like a huge scam to me.
If this is indeed a scam and you were scammed a googlewave account is not a fashion statement. Most people dont have a clue of how they will be using google wave even after getting an invite. Wait till google comes up with a wider audience with more of your friends/family on it and then get on the wave.
Till then stop coming up on my #googlewave search please.
