Perhaps a tad too liberal when players start to block others on a percieved threat rather than an actual threat or to stop harrasment (as i imagine it was the intended use).
Edit - jump into system, see a player unknown to you, block on the off chance they may or may not try to kill you. Thats pretty bad mechanics at play right there.
I don't think anyone's suggested that, not me anyway. Block engineers cheats, griefers, station rammers and noobsplatters or whatever, but no need to go crazy with it. Logging into solo would be far easier.
Could you try to source the block function being for harassment only thing, I've never had that impression from FDEV.
