if possiblw, you should go back through your chat logs and screenshots to find proof of these occurences. if you go through chat logs you can find timestamps of when the sieges occurred, who died, when, and to whom. and just general gathering evidence that these players did in fact send threatening messages and threats to you. go around your claims with a stick to find other claims and screenshot it. without even a single timestamp here, the staff have been sent on a wild goose chase looking for proof of this happening. if you need help looking for your chat logs, find me on discord and i can give a quick how-to (if youre on windows i can, anything else you may have to google it)

bottom line is, you need to give evidence of these events, else this report will be seen as butthurt and complaining.
