... For example: Ron Guilmette has recently pointed out that notorious spammer Scott Richter has apparently hijacked *another* /16 block -- 150.230.0.0/16. I've dropped that block into various local blacklists, and in some cases, various local firewalls. The entry is essentially permanent, because there's no reason for me to make it otherwise. Perhaps one day ARIN will yank it back, along with all his other blocks, and blacklist him for life; but (a) I doubt it and (b) I'm not willing to wait. The best course of action for me is to just consider it scorched earth and move on.
To the extent that you're aware of a fraudulently transferred address block, please report it to <https://www.arin.net/resources/fraud/>. Thanks! /John John Curran President and CEO ARIN
