AS3254/Lucky.net contact details

Hi,

(Disclaimer: I know this isn't the ideal forum, but some
people just don't keep ARIN/RIPE contact details up to date)

Does anyone have reliable, English-speaking contact details
for AS3254/Lucky.net? I'm trying to contact them regarding
malicious activity ("Hackers" to misuse the term) but I'm
not getting any response to E-Mails.

Thanks.
