Better modding in the past or too few mods working now?

Viewing older questions some look like Swiss cheese with the amount of comments expunged from the thread, even in social, for various reason from writing standard, unhelpful, the all-time fav personal attack, etc., but of late (and I have not seen everything) it appears a whole lot less moderation is going on as comments way off topic as to be greater than the equivalent distance that the Earth is from the planet formally known as Pluto, stealthy personal attacks, and such are left unaddressed in threads. Is it because there are not enough mods looking, they have gotten more lenient, etc.?
