There seems to be an error in the calculations of account balance.

If the Slave Rank on a page changes between the time it is added on a campaign and then later removed, it uses the updated amount instead of the original amount.

I now have no incoming or outgoing links, but my account balance is in negative.

2010-07-06 08:40:22 Ausgehender Link 1.67
2010-07-13 20:00:01 Ausgehender Link (vom System) gelöscht -1.28

2010-07-06 22:40:23 Eingehender Link -1.96
2010-07-07 17:00:08 Eigehender Link (selber) gelöscht 1.89

(Look at my account transfer page . . I have not listed the websites here purposefully.)

Dear user,

the payments are calculated daily.
So for example, if the link costs USD 30, you pay/get USD 1 per day.
If the link is deleted after 10 days, there is a refund of USD 20.

That's why the prices in your calculation differ.

With best regards,

It's not very clear for when you receive points without buying them, but that makes sense.
