That one always blocks for exactly what it says: extremely large additions. I don't know the context, but their extremely large addition (that you can't view, as it's on here) would have been disruptive if the filter let it through. I can't tell you how big does "extremely" mean in the context of the filter (as people could use that information to bypass the filter in the future) but as you could already tell no posts of yours have been that large in the past.

AbuseFilter extension does not have an option to set the duration of a block. Blocked users can always complain to me over my Community Central talkpage, as pointed out in the message that appears when blocked.
