All right, break it up guys.
Nobody likes spam, but we don't have to turn this into a personal vendetta. Just stay away from doing it in the wrong posts in the future, and everyone will be happy.
Banning someone for spam should be VERY rarely done though.
A good reason would be if a creative post got filled with
"giueshgi"
"igsejgiu"
"guieshg"
"bdrjkbnji"
"uighseg"
"igriugjhi"
...and so on.
That is a good reason for banning someone
