Alright, @Vector and I have done a little research and after reading these chatlogs, I can clearly see that it was his intention to troll.
Furthermore it is obviously not allowed to spawncamp like this with donator powers.
EDIT:I am down to give him a warning, now let's wait for @Liekos to respond!
In addition I do think about hiving him a (short) ban for his actions.
Edit: In case he has already recived (several) warning, I am down to remove his donator powers and give him a ban.
As it turned out, he has been warned several times already by @TacoSmasher47 and @TheSupremePatriot, I am down to remove his donator powers and give him a short ban.
