Depends on where the data is stored, if the owner of the domain lives in the EU or a similar jurisdiction the data will be under Database rights for 15 years. There is no such thing as community owned. Each post might be owned by the person who posted it but often that is not the case. EDIT: so of course you should dump the data, wget -r and dump it.
