No, it would be up to GMs to decide if it was harassment, they would look at all the evidence and make a decision, they would not be able to share all the evidence with you, though if you lost a ship and were reimbursed you could infer they agreed, they may also have just erred on the side of caution.
For instance it is legitimate gameplay to follow someone around and gank them repeatedly and curtail their ability to play the game, if the sole purpose of this activity is not just to harass, but to curtail their impact on the sand box.
Perhaps you war deced their corp because they were an ass in local, they dropped to npc corp and hid in high sec, and so you had to rely on bumping and ganking to ‘shut them down’ which is valid pvp.
One can also hire a Merc group to take on a player, with the contract fulfilled once the character is biomassed and the name becomes available again, the Merc group in this case would be engaging in legitimate gameplay, doing pvp for profit, and the originator of the contract would not be instigating harassment, if they could show in game reasons for desiring the loss of this character.
Now running a player out of the game would be something else, though can still be achieved without harassment
Just look at the judge and his full set of hands!
Never be a GM in eve if you want an easy life I guess.
Ps. Get out their on the pipe in a cheap destroyer and just try some pvp, prep the grid with tacs first, know the system, set your targets to orange so they show in local and to distinguish from the red flashies you can engage without risk, join AG see if they will teach you some stuff, hell join CODE if they will have you. Lots to learn, no need for ‘soulbound coat of gank expense’ x fly safe(ish its eve)
