As Nicola says, if this is a personal issue - even if there are a few of you, then you need to take it up with her directly.
NO one has to come on here, no one HAS to read what other people put. I am sure we all get narked by others sometimes - even on the net and the best thing to do is stay away as other epople will be how they will be, regardless of your opinion about them.
A bit like - there's load of crap on tv? Well guess what, you have an OFF button.
I am guessing after I read a post somewhere else about something that has happened to someone else, that all this is from an other forum maybe? And not something that happened on here.
Maybe you can't stand Nicola - but again, either stay away from someone you don't like or take it up with them, or laugh about it if you really think they are that bad.
If this was RL, you wouldn't be sending that perso mystery messages, as that would become stalking wouldn't it, so deal with it as you would in RL - surely the techniques I have said above!!
