Yes, I was on this server once, where there was only 2 owners, and a friend of mine. We literally had just joined the server for about 30 seconds, and he said: "WELCOME TO BLAH BLAH BLAH WHATEVER! IF YOU DONATE 5 DOLLARS, I WILL GIVE YOU 3 DIAMONDS!"
I, seeing this in the chat immediately start asking him about donations, and his server and what to do, since he was so "friendly" to us.
He then told me I needed to go and donate the 5 dollars or never join.
About 10 seconds later, I was banned for "Not Donating and Causing Issues"
Another time...
I joined a server, you guessed it, with only the server owner on. He welcomes me to the server, and does the whole orientation thing. About 5-10 minutes pass by and there is a broadcast, saying you could apply for staff if you paid for some ridiculous amount. I then start talking to him, just wanting to know about the site, and what not. He then gives me an adfly link, (link shortener that pays you 5 dollars per 10,000 visits) and says "Here is the link, click on it". And it takes me to some ridiculous homemade enjin looking awful site that I really can't explain. After looking at the site, I start talking to the owner once again, and he immediately begins to be egotistical. I simply ask him what to do and he told me to "shutup little kid, you go build somewhere." Immediately, I ask him why he's being mean, and he tells me to "SHUT THE F$@# UP, THIS SERVER IS TOO GOOD FOR YOU, YOU DON'T DESERVE TO BE ON IT, IT'S THE BEST ONE, EVERY YOUTEWBER WILL BE ON IT!"
Then... He bans me...
Egotistical server owners... Got to love em.
