Chip,
Given the other people that have been targeted, it is either Simon, or someone who has fallen out with the EXACT same people as Simon . There are just too many coincidences to be anyone else.

Obviously I am aware that there are going to lots of people who will dislike my views / attitude, as I personally feel I don't see eye to eye to with several on this board. However, I cannot think of one that I have fallen out with that could or would (be bothered) to do the things that have been done and if I had been the only one to be targeted, then I would except your explanation as being feasible.

The fact that several others have also been targeted - all of whom have fallen out with the same person and all of whom are publically vocal about their dislike for Simon (with one exception, whom it wasn't publically known about their fall-out - yet he was still targeted), then it makes it unlikely to be anyone else.

Even though I do not see eye to eye with Simon and 100% believe he is the PF Hacker, I would still not have the vindictiveness or inclination to do what he has done (even now that he has deleted these threads).
