Now Martin and Angela are cooperating in vandalizing my home page, despite my repeated pleas to stop harassing me. And no one on the Wiki-En list seems to have a problem with their harassment and vandalism.
This has probably been explained before, but I think you're overreacting to something that's not really an issue here. As far as I can tell they didn't edit your user page at all, only your *talk* page. The talk page is a message-board of sorts, in which people can ask you questions or make comments directed at you, and you'll notice them through the "you have new messages" notification. It's not in any way your personal page, just a place for people to leave you messages. So adding a message there is fully in keeping with its indended use, not "vandalism."
I think most of us here are fairly reasonable people, so if there were actually vandalism directed at you, even those who generally disagreed with you would agree it was unwarranted and do something about it (so there's no need to take retributive steps instead). I don't think that's the case here though.
