Is it possible for me to place sexy ads on my website along with Adsense

I rejected my google adsense, if i want to register join google adsense again am i eligible? what can i do?
If i use back the same computer? still can participate? cause google is based on GUI .

Does Google use ADSENSE publisher IDs to BAN sites from its Index?

ok i have made an account with adsense a month ago,maybe more than a month,since than i started spending hours & hours on internet in order to understand it,i got disapointed many times & left adsense
i made a blog,a website….though it was a hard task,i got ads to display but
- the ads are irrelevent completely to the content of my site,why would anybody click them
- the ads are only appearing in my blog (blogger.com,coz there’s a direct option for adsense) while in my website no ad appearing & the code is displayed in that way when i publish it
- since then i’ve added adsense,(more than a month) my earnings are $:0.00,im disappointed & i think im waisting my time
the only thing which urge me to be there is that there are certain people,who’ve started & within a week they’ve started earning,maybe less or very less like 20$ per week,but atleast they’ve started
but my earnings are ZERO since the 1st day,i feel like gosh i’ve wasted alot of time,even if i’ve earned a few bucks,it is enough to convince me that yeah this system works
anybody expereinced pls guide me,is anyone outthere new to adsense & have started making money within a week or so????
secondly my blog have just a few (maybe 10) hits a day
& yeah what is the meaning adding channels to your list,when you goto asense setup tab,manage ads,it asks in step 2….what does it mean?
if anyone expereinced outthere could helpme,i would be really gratefull
thanks in advance
