Welcome to WebmasterWorld Guest from 188.8.131.52
For those that want to argue that accounts are not capped for earnings I have many years of hard data to prove otherwise.
The only thing capping your site is your imagination.
These drops and spikes happen all the time, to different people. April 2010 is likely nothing different.
/shrug if thats not an account cap I sure would love to know wth it is.
I want the rest of the day, which is often parking my carcass in a pub with a pal arguing over the hot topic of the day :)
