Scrape all posts of a user/scrape only new posts

[freshmre]

I want to get all of a specific user's posts. What I'm doing now is ./Urs.py -u URS_test 9999, but that's making redundant requests for controversial, hot, guilded and top; 403's if the number of posts is suffiently large and creates an output many times larger than it should be. Is there a flag for new only like there is for subreddits? Or ideally a way to get all user history?
