appreciate of

"I would appreciate of this book." comments a guy on Facebook from Dothan, Alabama.

Appreciate of? Where did that come from? I assumed, correctly, that my find wasn't a one-off. A quick Google search turned up:

If you have items you think we might be able to use, or if you would like to contribute your time to assist in one of the many projects we have on-going, we would appreciate of these contributions, as well. (Georgia, US)

There's also a suspiciously large number of instances of "would appreciate of" that clearly mean "would appreciate (it) if". I suppose these could all be typos, but perhaps there are people who actually say "of" in this context also.
