It has come to my attention   a player named Stewie_94  kept placing blocks in another a player named TARDISCHILD's house/base.

after repeatedly being asked to stop, he kept placing blocks.

Here is a screenshot.

I also saw him earlier insulting staff after being told to stop

You do realize there were staff online at the time right? There was no need to make this post. You even took a screenshot of a staff member.

Sorry ignore the above.

I did notice the player being a nuisance and warned him to stop a few times. I was not aware that he did not heed my warnings. If I

see this behavior continue I will punish the player causing issues accordingly.
