Well if it was me on the receiving end of such messages, I would also say "Bring it on." It wouldn't faze me in the slightest.
Problem unlikely to arise here as I'm not a member of AW and there is no OH either.
Sadly as we know only too well, there is a tiny percentage of people in this game that are 'sick in the head' running their own twisted vendetta or campaign for what ever reason that spoils it for everyone else.
They are too thick to realise that with today's modern technology, information is captured electronically and stored and electronic trails are created and that their malicious actions (even anonymously) can easily be proved should the need arise.
If it starts getting really serious, then there are various laws that cover this sort of thing.
A friend of mine (not a punter and happily married) is about to find out just how effective these laws are.
Over the past few years, he has been on the receiving end of a vendetta from various others affecting his home life, work and personal interests and so on. He moved house to get away from the problem and they eventually found his new address.
Finally, enough was enough and he has just launched a Court case to sort this problem out once and for all. From what he has said, some people in the near future are about to get a bit of a surprise from the authorities. I have asked that he keeps me up to date with developments regarding this.
Going back to punting problems, if any issues do arise in the future, then there is always plenty of advice and support on here.
