"His post about deletions was moved to his thread about deletions. I moved the second one, and deleted the first, as we do with duplicates. I will continue to do this if he posts it again."

OK, work with me on this.

"His [the Shambles] post about deletions [from another thread] was moved to his thread about deletions [deletions are things that have been taken away, either mysteriously (or ostentatiously in this case)]. I [a clone] moved the second one [the one that's here now], and deleted the first [the one that isn't there now but is now here], as we [clones] do with duplicates [but now there are no duplicates]. I will continue to do this [OK] if he posts it [the post that isn't anywhere but here, right?] again."

EUREKA

In plain English, the thing that isn't there anymore is gone. WHEW.
