Well in that screenshot, I can't see that he spawnkilling you. No death list at right side, No death message at chat and no clue about he is going to kill you. Looks like he was aiming at you.
Also you have been just jailed a day ago for spawnkilling:

Good to see you doing right thing and started to report people already. But please firstly report ingame and then be sure to take a clear proof next time! Thanks for reporting anyway.
