Hey man, not trying to act like a staff member but post it on the player reports forum page. This isn't where you post reports bro
A simple fix to use when it's happening is using the command /tptoggle This will disable all tp requests to you until you /tptoggle again An important command that everyone in factions should know.
Yea sadly that happens alot bro, not the most mature people sometimes, just /ignore them and move on.
