mod discretion applies here. talking about shipping a 10 year old with an adult should be deleted, talking about shipping a 17 year old with a 19 year old shouldn't be, there is a huge amount of grey area in between that that the rules don't directly cover that should be dealt with on a case by case basis.

i would delete anything minor/parental figure on that basis, but i'm not familiar enough with several wiffu-popular canons to necessarily know if a character being spoken of is underage.
