I hate to tell you this, but you can't find out. Team Fortress 2 is the default servername for a server. This means that if a server does not specify a name, it's given this one. The person that owns the server probably put a password on it so that only people he or she knows can enter.
My advice: Just play someplace else
There is no legitimate TF2 hat generator, or else hats would be worthless because everyone would have them
I am having the same problem, have you fixed it yet?
It is a random item drop
Yes, you can receive hats from The Item Drop System.
Through the item drop system, achievement milestones, crafting or trading.
It is a special item that can only be obtained if you played on the days of when Meet the Pyro came out.
The majority of items in Team Fortress 2 have levels associated with them. Levels, viewed with the item name in the loadout menu, are purely cosmetic and do not modify the effectiveness of any weapon or item however, some levels may increase the value of the item in trading for example, people may pay more for special level items e.g 0, 1, 42, 69, 100 etc.There is a table on the Team Fortress wiki that contains all the levels of the weapons and items.
An unusual item is an item that has an "unusual" status. It's name is always purple, and the item itself will have a particle effect around it. They are considered extremely valuable and can only be obtained naturally through crates.
Sadly no, once the item has been deleted you can't restore it, you need to get it again from item drop, or crafting.
The Dead Ringer is an unlockable achievement item for the Spy class. The item can also be found via the random drop system, crafting, or trading.
You cannot subscribe to items on the Team Fortress 2 workshop. The workshop is not like most other workshops. Users make hats and weapons and upload them for Valve's judgement. If Valve approves of the item, they get put into the game.
Levels are purely ascetic. Though some level numbers are more popular than others.
fabricate is turning scrap into an item, rebuild is turning items into another item (rebuild 2 hats into 1 hat)
