Backlink Questions.

I have a blogspot blog and I used dot tk to give it a shorter domain.I've been using PRstorm to get backlinks to my dot tk domain.The harvester i'm using only harvests urls from yahoo.I ran PRstorm last night and i'm running it as we speak.I have 0 backlinks with google and msn.They say if you get too many backlinks fast,Google will throw the dominating bitch slap on you.Well seeing my backlinks with google is 0,they can't touch me, right?And,seeing i'm basically using a sub-domain through dot tk,my original blogspot url should be fine?Right?Currently my blodspot url only has 7 backlinks.My dot tk however is getting about 120 backlinks every time I run PRstorm.Any input would be fantastic.

Thanks In Advance

Think you are safe. Send some traffic to your site - helps too.

I'm getting about 500 hits a day.

But seeing i'm using a sub-domain getting my backlinks with none of them being google,means google can't touch me,right?
