State your appeal: I am actually very confused about this. What roundstart suicide? How is that antag rolling? etc. I do not remember this but I think I had to leave or something so I just killed myself. Not sure.

If you suicide at roundstart it will be seen as you not wanting to play the round as a non antag, which is antag rolling (playing the game only to be antag/suiciding to play as midround antag)

The ban is correct so this is denied.
