20371 is one thread (4 messages), and was removed 32 days after the initial post.
20375 is a separate thread (only one message) and was deleted immediately.
Sorry there's not enough information about the first version of the forums to allow a meaningful analysis - it is, however, interesting to look at which entire threads in the second version were removed and which were allowed to remain (based only on subject line).
For clarity: the file only deals with the second version.
