I feel like this fits right into bad counterplay. Where your options are reset the activity to escape or block to prevent instancing.
This is one of those paradoxes where fairness unintentionally promotes bad counterplay. We need the different modes of play to be fair, and we need the block function. Personally I almost never use the block function to block gankers, but there are harassment issues that make it a necessity. Unsolicited advances in PMs, racist or sexist chat in comms, being a pad hog, etc.
The only way to solve bad counterplay with these implementations of fairness is to have Open only play and to remove the block function. That's never going to happen in ED, and I'll go back to that pastel nightmare NMS if it does.
