Removing the never boot option will only be a fix going forward. Since I plan to scrutinize every game and tourney I enter from now on to avoid this issue, and since Fizzer has also added a warning that apparently pops up (I haven't seen it) if you are about to join a never boot game, I'm less concerned about this problem as a future consideration than I am about how to fix games that are stuck now, which is the subject of this question by Sir Frederick.
My UserVoice proposal, asking that users be allowed to contact Fizzer after 30 days of inactivity to request that games become unstuck, is here:

Please vote for this if interested.
Ruthless' proposal is another good one. If we can't get these games removed for whatever reason, at least perhaps we can stop having to see them.
