I'm not really happy with that. Landgrab appears to be a Freemium game, and that's borderline commercial. At the very least, asking would've been good.
I did that very long ago, I didn't really think of suck things back then (nor did any other BM player I was in contact with as I made it), and the possibility of non-BM players playing on it, given how fugly it looks, had not occurred to me either.
I haven't connected to that in years, but if my account still exists, maybe I can look to see if the map can be deleted, if you want.
