Tony,
Thanks for responding. Yeah I called support, they looked through things and didn't see an obvious answer. They suggested I go through every folder and look for very large files. I looked through all the folders that had been recently updated and the only kind of large files were the backups. I deleted most of those, but there is not much of a change in the disk space usage, still over 12GB.
One of the support people I talked with told me that it would not be caused by something in ny MySQL databases because they are stored on a different server(something like that), but since I did find that one result with spam words there (from rngdmstr's suggestion) I wonder if he was wrong.
I'll try calling tech support again tomorrow.
