Google Ban

Okay short question here but this happened to my 2 lately made autoblogs so i wanted to ask if maybe you know what might be the reasons and is it a ban.

After 1 day main pages of both blogs got indexed. But now when i look to dc there are not anymore. When i enter google webmaster tools it says that google did crawl my site but none of pages are indexed.

Does that mean a ban or it just happends with new domains sometimes ? [i had situations that new blogs disappeared from serps but then came back].

Thanx

edit: actually since you are talking autoblog someone else should respond I haven't used them

Well but mainly it is a patter of ban or not really? I just never seen such situation so even answer not about ablogs is fine [didnt see yours before edit]

def. just a sandbox issue. wait a bit, and they'll be back in the index.

Seems in last days sandboxes are beeing faster than usual
Anyways if thats not normal scenario of ban thats nice, i just didnt know how to read it.
