It has nothing to do with Mamdani, for those of who don't want to bother to read. Most of this occurred under Eric Adams's watch.

Anecdotally, I do think covid made people a lot more aware of how deeply backlogged the housing courts are. It seems like a lot of people (like the anonymous one in the article) realized they could not pay rent and avoid being actually evicted for quite some time.

This is a recurring theme in city problems: Backlogged courts. Sometimes that's to the benefit of the less fortunate (here), but it also often results in terrible outcomes (see: Kalief Browder).
