I got banned on a server with 2 guys who had the same name. (Darthmaul7 or summat) This was a while ago but still mildly funny.
They were playing on the space station map and I couldn't think of anything to build (like usual) so I looked at what they had built/were building. I got kicked for the reason "Don't go in r house noob!" or something to that extent.
I went back, didn't say anything and started to build my own house. I made a roof and locked the door. When he tried to get in but couldn't he repeatedly clicked the door so it made that obnoxious DENIED sound over and over again. Then, right as I was finishing the TV, he deleted the roof and went in my house. So I deleted the floor and went in his and was banned for the same reason before.
I went back and asked what was with the hypocrisy. He called me a noob and told me not to go in his house. Well, that was a cool little house I'd made, so I started making it again and he deleted the floor and started putting 1x1s on all the platforms so I couldn't build. I built 2 1x1s and started building. Then the 2 of them started calling me a noob and being friendy starfishs and saying I had no building skills and all that. I argued with them for a while then asked if either of them knew how to do anything other than make spammy builds, and if they even knew how relays worked. It got quiet for a bit and they banned me.
TL;DR: Got kicked for going in their house, he went in mine afterward so I went in his, I got kicked for that and later banned for insulting his/their intelligence. (Pronoun nightmare I swears.)
I admit though, I am not an amazing builder. At least my builds aren't made of 1x2 bricks.
