I do not have season_packs: yes for any of my series, yet occasionally I get a series pack. For example, yesterday one downloaded, and I do not know why.
Here's the log entry:

I have dozens of shows in the config file, and I rarely, if every get a season pack. I usually just delete them a move on, but I figured I would follow up on this one to stop them in the future.
