They really didn't specify what "abusing" means, so I don't know how you could infer that from the article. For all we know, a person who is an abusive user means a person who holds multiple leases on separate apartments where a no-sublet clause is in the lease, and rents all of them out simultaneously (pocketing the difference over their rental rate) while providing no further services other than a key drop. They also drew a pretty clear line between the time when (a) "we banned some users we considered abusive" and with (b) "the state of New York asked for information pertaining to a subset of our users in New York, which had a substantial intersection with our banned list from (a)". It's also clear from the article that they don't know what criteria were used by NYS investigators to select 124 users for closer investigation.
