NOW HEAR THIS: T-Rain is fucked. You can get young rain, you are already #1 in google on my search here:
http://www.google.com/search?q=young...L_enCA289CA289
Yes it comes via whois.domaintools.com/youngrain.com not youngrain.com but it is there nonetheless. You can easily build up youngrain.com you can not easily build an identity "on the web" as t-rain.
You can build up youngrain.com and use the name t-rain it still won't work for search immediately or at all unless you become successful and have backlinks and buzz about you. Gfy does not count.
