DN Rules are ridiculas?

So I wanted to play some Roleplay with some people and I did This :

I put up a duel request which said "PM me to play some roleplay"
I got banned???
So I consulted a Game-Master on the Dueling Network to ask what is the reason that i was banned for?He answered like this - Hosting a Duel with a note that asks a member to PM or otherwise contact them for trades, sales, tournaments, teams, duel password, videos or anything except a custom ruleset of that duel.

The words "anything except a custom ruleset of that duel " were underlined. I see roleplay as a custom ruleset and yet i was still banned, he said that my description was unclear???

I am super confused by this, I want to know what you guys think about this situation and post some more funny rules or punishments on DN

PS. I will be unbanned in 1 day ^-^
My current DN account while i am banned is polkapolka1

The problem was solved i am unbanned
