I don't know what you're seeing, but in my display, I see "101101" as the author for replies #83, 87, and 88 in this thread. This post that you're reading now is reply #92. If you're seeing a lower number, then the forum software is adjusting that because -- I presume -- you've got "101101" on Ignore.
I'm not suggesting you shouldn't Ignore him; I did for awhile. But it was too confusing reading replies to his posts which omitted even the bits quoted in responses to his posts!
I definitely don't like how this forum handles the "Ignore" function. If it's actually showing different response numbers in a thread when you have someone on "Ignore", then that's even worse.
