Mark,
I'll try to make it short :-)
In the past, you have been considered bordering vandalism due to a couple of weird actions.
As of today, I think you are recognised as part of the community and most would agree you are an important element in it, even if not all will always agree with you.
The fact is that you flood this mailing list. It is embarassing readers. You are correct that they can delete your mails, or jump over a thread.
Still, I think you sometimes say important things, and these important words are lost in the amount of text you write. This is not beneficial.
