Trashwiki is a non-profit no-budget project. The domain name, server space and tech support is happily provided by guaka. There are some other people with access to this server, but they're all trusted people who either dumpster dive themselves or otherwise have the right spirit (e.g. Wikimini is running on the same machine).
We won't sell your email addresses or names to anyone. Whatever you write out for the public (and Google, and spam harvesting bots) to see is your own responsibility. We are trying to block spiders through our robots.txt though.
