@Raked - please refrain from sharing login credentials publicly. We've hidden them for you now but it's never advised to share that kind of information when other publishers or visitors can see it.
Regarding users logging into wp-admin in some way, and not seeing ads, that's actually exactly how our system is designed to work.
Logged in users should not be seeing ads.
There are other ways of allowing logged in users to have a profile that doesn't involve logging into wp-admin. If you can provide more information on how you've implemented the creation of accounts, we can advise further.
