---- DO NOT TRUST HIM WITH YOUR PRIMARY KEY ----
Zedrow is a known forum troll, key phisher, and just in general problem user.
If he doesn't steal your keys in the form of asking for them so he can enter them, there are methods that are readily available to extract keys from keydats, which he will have FULL ACCESS TO. By running a server on his service you are literally giving him your key so he can use it however he wants.
If you ABSOLUTELY CANNOT live without this hosting service, buy a new key for you to use for only dedicated hosting.
