Within the past day there are no posts of yours that have been deleted. So... That means a thread you posted in got deleted. I'm not sure which one since there are tons of deleted threads.
If you did spam or break some rule, you would have been infracted/banned for it. You weren't though... So you didn't do anything. You should've noticed that. You only make threads here if you were abused by a staff member or believe a staff member's action's were unjust. Since you weren't abused at all... And since whoever's thread was deleted can only dispute if s/he feels that the staff member's action's were unjust... Then it shouldn't be your concern.
