No limits after your 10 days. Maybe later on in the day, but yes after 10 days it is removed. It has to be 10 ACTIVE days also. I think 10 per day would be good, but you probably do far more.
As for the limit, no I can do a thousand hits in a day sometimes. I wake up and start drinking coffee at 3 am, and up till 9 or 10 sometimes.
