To add a little more, compat's apispec is a very large library around action=query, list=blocks , but it is *unused* in compat (according to $ git grep apispec)

http://en.wikipedia.org/w/api.php?action=query&list=blocks

core has Site.blocks() which lists all blocks with parameters:

starttime=None
endtime=None
reverse=False
blockids=None
users=None
step=None
total=None

What functionality is needed?

At least, unblock. For example, when having a list of lots of IP addresses that were infinite blocked that I want to unblock

@Ciencia_Al_Poder, agree, I had the same need once

[pywikibot/core@master] Some compat apispec functionality could be used in core

I wish that in the future I can get a delete.py readable list of users and pass them into a block.py script which mass blocks them. Any progress towards any form of block/unblock script yet?
