It is legitimate game play. You could…
Wait till downtime. You will be removed from space and can log in when the bummer is busy.
Bring an alt or trusted friend to web you so you will warp away faster. Do not trust a random 3rd party who wants to duel you to provide webs. This is a trap.
Do not pay a random. It too is a trap and will only mark you as an easy target.
Also… Treat this person as a bully. That may sound odd and be viewed negatively but in essence, that is what this player is. They have an opportunity to make themselves feel better by holding power over you. Do not feed them. Do not give them money. Do not give tears in local or spew hate filled emails. It fuels them. The best course of action is to ignore them. Do not give then the attention they are craving. They will move into another target once they realize you ate not providing sport for them.
And welcome to EVE where it is a harsh world and this happens.
