Avoid trackback of one's own posts

It would be nice to turn OFF trackback on one's own posts. For example, if I link to a previous post I made, trackback automatically pings that post and generates a trackback comment there (attached to the old post). While some people make like this, I find it kind of annoying. Besides, tracking back to oneself certainly seems like self-indulgent behavior on the part of the blogger (when it's really the module doing it automatically).

What's more, all the trackbacks get posted as user/1, no matter who is making the linking post. In other words, if user/11 makes reference to another post on the site, the trackback gets added to the linked post as coming from user/1.

I'm posting this as a feature request, not a bug, since it seems to be a design issue. I'm posting it as critical because lacking this feature creates behavior that is virtually bug-like. Being able to turn off trackbacks to posts within one's own site would be an easy fix for this.

Note: There also seems to be a potentially related bug in trackback where sometimes it pings other posts at random. I already submitted this bug a few days ago, but mention it here in case they might be related.
