List of homeowners names for HOA by leased land park owner

I am the president of a 12 year old HOA in Florida. We own our homes but we are in a leased land park. The owner of the park has recently notified the HOA that they will not be supplying them with a list of homeowners in the park. We have been getting this list several times a years from park management. We believe the issue is that we have been complaining about unauthorized renters within the park. Homeowners are not allowed to rent their homes but park management has a rent to own program on homes they own. We also found many valid homeowners not updated on the parks list. Homeowners who have moved, died or purchased other homes and sold their old homes are not accurately listed on the managements list. When we questions these issues with park management we were told that, because of "privacy" issues the HOA would no longer get a list of Homeowners. How is the HOA to verify a valid homeowner who can join the HOA and have voting rights if we can't identify people by ownership. A rent to own resident would have the address in our park as their address so that is not valid. Since they don't own the home they can not join the HOA or vote until they complete the sale of the home. Is the park owner, a large corporation, required to supply, the HOA will a homeowners list?
