Reason: broke the rule "Only submissions for this jam are allowed"
Next time you should make the wording for the rule more clear, because
Only submissions for this jam are allowed
sounds a lot like
The lifespan of an onion is determined by how long it lives
: one could think
¡Of Course only submissions for this jam are allowed; otherwise it wouldn’t be a submission for this Jam!
in the same way that they would think
¡Of Course the lifespan of an onion is determined by how long it lives; otherwise it wouldn’t be the lifespan of an Onion!
. much better is something like
Submissions must be just for this jam and not for other jams
.
