Server names with squares?

[Plasma]

I've noticed that a bunch of server names what some sort of strange character (square like) in front of their names. anyone know how that was done? :?:

It's silly really since most people who sort by name are looking for a particular server.. They put the boxes so they can be at the top of the list. Most will sort by ping, gametype, map etc.. so putting the boxes only limits what you can put in for your servername and gets you a bunch of inexperienced players who don't realize they can sort other ways.

they are trying to get to the top of the game browsers. Kinda like being AAA Towing Company in the phone book. ;)

Thing is they are the first servers I ignore when doing a search...doesn't pay to be greedy.
