(S)He doesn't really delete it, just empty it. You can revert it easily. Block the IP, as long as you can. You can also choose to lock your wiki from all anonymous editing, but it's best to discuss that with your community first. If you decide not to go for that, revert, block, and never show any sign of frustration. Stay Zen.
