Why the forget are you making a steam account just to host? Why not just authenticate???
Because after 4 hours of research, it seems that only Badspot has the ability to make the game use SteamID's (a number such as STEAM_0:1:25759419) for authentication.
Non-developers can only use the
web API, which provides statistics about the user. I do not know the source code of steam_API.dll or Blockland.exe, so I cannot find out the process for using a SteamID to authenticate a
game.
And by the way, after more than 4 days, my Steampowered forum account is
still in the moderation queue for the forum. That's about the only place I can ask questions like this.
But I can hire somebody else to figure this out. I could give them 6 months of free hosting on HammerHost.
