The emails are bizarrely sloppy with spelling and punctuation, perhaps many usages of "don't" ended up being typed as "don t", triggering an automated find-and-replace.

The export itself is also sloppy, with characters like equal signs being added in weird places. Seems like they have it set to cast a wide and poorly set up net.

Equals signs substituting in some places.

Looks like the result of quoted printable decoding done by inept regex.
