That's a fair point... But more an issue with the (abuse of the) block feature surely though?
ps: Don't think the block feature is quite as black and white as you might suggest though?
I agree with your PS and suspect the block function isn't quite as black'n'white the way we think it works, but it does do *something*, and is a valid in game facility, so any use fundamentally can't be labelled "abuse", since E: D is by design a pro-choice game, and extends many ways for each player to choose how they wish to be instanced with other CMDRs...
... hence threads like these.
