Seams to me that o got baned whyle trying to solve the nasa level, after six minutes of playing... wich is kinda .. weird for this type of game. I don't like it anymore... 
I've been looking at logs so the most anyone was ever banned was a couple of minutes.
And BTW, it only bans on the first level, and only with a 0.05 probability, and only if
you feed it the wrong URL (and you are warned of this). Come on, don't make the server
grab stupid nasa.gov url's for no apparent reason

Though even if you do, i'm unbanning
you I just don't want somebody making hundreds of nasa.gov requests using the haxgame
while I'm sleeping etc.
As for the game, it looks like the challenge is getting real - there are now a dozen users,
two of them above level 10, and many who have the potential of getting there.
The current toplist is:
Top 10 : 1. liteonish (16)
2. zer0 (15)
3. jamrun9 (6)
4. packetdump (4)
5. waraxe (4)
6. Sapient200 (2)
7. Corbin (2)
8. SuRGeoN (2)
9. nights (2)
10. reset (2)
ps: instead of getting banned by feeding obviosuly wrong url's you could have searched
google for 'search site:nasa.gov' pushing 'i feel lucky today' or something, and there
you go.
