The laziest thing to do is to not do anything and let someone else moderate. While the disagreements over moderation are normal, complains about volunteers being "lazy" for not doing impossible are absurd.
Hardly. Volunteer positions come with responsibilities. No one is forcing them to waste their time on moderating an internet forum, but they chose to do it for whatever reason and then chose to be lazy and actively harmful.
The complaint here is about moderation tactic that is not actively harmful or abusive to people and ease their own load when threads become too much. Complaining about that is absurd.
