Why was I banned?

I believe it was for this thread: http://www.sythe.org/showthread.php?t=596896

But I don't know why? I think it was Sin666 who banned/infracted me thus giving me 3 infractions.

Could you explain why?

By the way, I am Kayosman but cannot put anything in the username box.

 

Vouching is not allowed to be used as a currency. Read the sticky located here:

In your thread, you asked for free training, and promised a vouch as payment.

Since that was your third infraction, you are banned for two weeks.

But you never did receive a warning so I reversed the "stickies" one and gave you a warning. You're unbanned.

 

And yet, all three of his infractions have been for not reading stickies. >.< But true, he should have been giving a warning first.
