COMPLEX SoftBank was the first pirate BBS ever busted in Finland.

The BBS was raided in November 1991 [1] and the Finnish computer magazine Mikrobitti interviewed the sysop in the 04-1992 issue while he was waiting for the trial to begin.

There is currently no certain information, that the BBS was affiliated with any groups even though it shared part of its name with the well known Finnish demo group.
