Real life. Some 'rbl testing' companies make money by monitoring rb's. Some rbl testing software includes blocked.secnap.net Seems to come in spurts. Won't hear from anyone for months and months, then for about two months will start getting emails and calls 'you are blocking my email'. And, yes, we get pretend lawyers call. I assume pretend because I can't imagine any lawyer actually taking the time to call about something so stupid: host -t a 131.70.175.193.blocked.secnap.net 131.70.175.193.blocked.secnap.net has address 127.0.0.2 host -t txt 131.70.175.193.blocked.secnap.net 131.70.175.193.blocked.secnap.net descriptive text "Private list. secnap.com use only Not licensed for public use.
