you should edit the ticket and change the Resolution field instead of editing title to closed.

FredX, the issue you linked is private I think, when I click on the link I get to a access denied page.

edit: @fredX Sounds good to keep that private.

Yup, learned the hard way not to long ago. https://www.youtube.com/watch?v=gIyZTS0qRjk

In the mean time, if you encounter a hacker and manage to kill them, check their pulse immediately. it will tell you their name until they respawn, then you can report the name to a server admin.
