Yes, I hope that in such cases a few words from you before or after would illuminate the game situation?Your last point is a problem though and one reason why block is vastly too powerful.
Even if you are minding your own business, I might have legitimate reasons to blow you up.
Take my threadnought in PvP, I tried to blow someone up for BGS reasons -> got accused of ganking.
Communication in a game where escape takes 15 seconds or less, makes no sense preemptively.
There are umpteen threads of people getting "ganked" in Deciat in Anacondas or Vettes. All Elite ranked noobs?
And yet more threads about people getting "ganked" by opposing powers. -> legitimate kill, unworthy of block? Yes but it happens.
Or explorers who absolutely insist of handing in in their paper ship in open in ShinDez. Only changing one variable would have been enough.
All these examples tell me
a) block is vastly too strong
b) you should never blame me, because I have reasons to kill you and you don't know them
c) there are people who aren't nice in this game (gankers, pad blockers, fleet carrier abductors etc.) Play accordingly.
The only people I've ever blocked have been:-
One guy who dropped in to a NHSS with us specially to mess up a fight with a Thargoid - clearly no game benefit to him.
The top few on the DG2 leader board (I put deliberately disrupting an event like DW2 in the "scum" category) - no game benefit to them.
People who attack with no comms in Deciat - obviously hoping to find new players in unengineered ships, maybe at the end of a meta-alloy trek.
