RTG are too stupid to mask their number beyond 141, sure some of them will end up in s*** for it.
even if they did put 141 infront of it, the person could still trace them if he/she took it further with the police or whatever.
How exactly did they get their numbers and from where?
That's what I mean, there's ways of using proxies and disposable numbers, but 141 doesn't let you hassle people without being traced. Guessing it's numbers of mag colleagues or 'mates' they're giving out.
