No, using Datastorm is not an offence in any server rule of Discovery, any more than looking at strategy guides for World of Warcraft is a bannable offence on a WoW server.
I used datastorm before, i still use it, but only to see ship stats when im not at a base, and weapon stats. I found out that you can find jumpholes and bases easily by following patrol paths:)
Discovery does not contain any secrets so well-hidden that you'll never be able to find them in-game. This mod
tries to be logical in placement of bases, jump holes, and wrecks. So please search yourself, and if you search well,
you'll find everything without spoiling the game with the Datastorm. For your own enjoyment!
As an alternative, you may always visit our forums at http://discoverygc.com and ask members about what you wanted to
find, or simply log on to our server and ask other players.
I hope you are capable of playing fair.
