I think this one got lost in the shuffle.
Anyways, the spawning 2x in one round IS against the rules, so make sure that you don't do it in the future, otherwise you may end up getting a ban.
Also regarding the report, based on the timing it does look questionable, especially considering you reported someone who mentioned having evidence to ban you.
However since you haven't been banned before I'm going to give you the benefit of the doubt and let you off with a warning.
Locking thread.
