Automatic flagging just means their algorithm is crap. Which is bad, but it's a fixable technical problem in the medium term and the post can be restored in the short term.

If this were deliberate flagging it would mean they were way outside of any reasonable interpretations of their guidelines and users really could no longer post anything and be confident it wouldn't run afoul of those interpretations. This is much harder to fix, and the confusion it wod cause is significantly higher.
