Unfortunately, no. I think with a little more diligence I could have done something, but the reporting would have been very limited, anyway.
If I remember correctly there is a database table that is created called something…”cache”. Not sure about that, though. Each entry is posted in this table and when an item is deleted through the WP interface it is not deleted here.
I can’t remember what the data format is for the type of entry that is made, but instead of being a row for each entry it combines all new entries in a sigle data field in the database using some abbreviated code. I coudn’t figure out how to parse the data and remove what I didn’t want.
In the end I just ended up manually entering all surveys in an Excel spreadheet…what a pain!
