They most likely don't want to target you in the first place.
Yes, they're doing mass surveillance, but for the targeted stuff, they still have targets, and most of us won't make the list.
The bar seems quite low
"These variables define terms and websites relating to the TAILs (The Amnesic Incognito Live System) software program, a comsec mechanism advocated by extremists on extremist forums."
There is a huge difference between matching some of those criteria (which may cause your surveillance data to be retained longer) and actually being targeted for active attacks.
Regarding the longer retention, the Linuxjournal article says that "the Tagesschau story provides new details about how the NSA's XKEYSCORE program decides which traffic to keep indefinitely" but I found no such information in the Tagesschau story (http://web.archive.org/web/20141005083429/http://www.tagessc...)
The consequences of having traffic to one of the tagged sites were never really publicly explained, always just "THE NSA IS WATCHING SPECIFICALLY FOR (random thing the NSA had a selector for)". Given how many people match each of these selectors, just matching one of them can't mean that much.
