Dear Sir from LACNIC!
your suggestions are impractical, you seem never have been
an administrator, and you seem not to know your own mandate!

There must be a working abuse contact in the WHOIS db,
and that contact must process the Abuse Reports caused by its clients,
and cut off those clients who are evidently doing cyber crimes
like attempting to hack other systems.
If that contact evidently does not do its duty, then it is
the job of the RIR to make them obey the rules.

FYI: here over in Europe (RIPE) "abuse-c" in the WHOIS has become a _mandatory_ entry
--> https://www.ripe.net/ripe/policies/proposals/2011-06
and it works in about all EU countries.
Problematic countries are CN, IN, ID, BR, RU, UA etc.
One wonders why...
I think because of lack of law & rules, education, and moral values.
