I think you failed to explain that, in Thailand, wiretapping is commonly performed by people illegally having free Internet access, against which MAC address is used, in vain, to identify true users.
it simply boils down to mac cloning,
Of course.
My question here kinda is, how to permanently get rid of this evil in an effective way,
Let access ISPs use TDR (Time Domain Reflectometry) to detect wiretapping, which requires periodic monitoring, which costs. Or, though less elegantly, password protection by something like PPPoE may work, which requires initial cost to change equipment. Anyway, preventing free riding should increase revenue of the ISPs.
and who to contact?
ISPs who want to protect paying customers (maybe, partly from your blacklisting).
(yes, I tried to get through to NOC's of the affected providers),
ISPs can do nothing, unless they know how to prevent free riding by wiretapping without harming paying customers. Masataka Ohta
