Hey!
I understand that you might be young and not understand 100% what is the big deal about you reuploading fanfics that are not yours here.
I promise you 100% that it is not ok. Put yourself in the author's position. If 50 people tell you this is not ok and explain to you why, don't take it the wrong way. The author, Ada, left this fandom because of the bullying they received here on wattpad.
I hope you understand why it is ok not and the fact that Ada left us a drive of her fics means a looot more than you can image, because some authors just delete everything and leave.
