I run a small 1.7 server with 10 slots and 512mb memory (75p per month).
Last night or early this morning someone had apparently gone on the server and loaded around 200 more chunks to the server in one long ugly line. View the Dynmap here: 62.210.203.102:8250

I will install something to limit the map size and growth In future, but this person has loaded a ridiculous amount of map, I'm guessing they where trying to troll because they had been kicked various times for 'not allowed to fly' by the console, and kicked for spamming.

Is it possible I can just get rid of all those chunks by some commands or plugin or somehow? I don't want to regenerate them like all the other post say to do I just want them gone. Out of my life. Forever.

Thankyou dearly for helping me by reading this!

Edit:
going to try downloading the map then using a map editing program and only export certain chunks
