I'm active reader. If fanfics that i subscribed, i always vote & comment cuz i think that all author when they update their fanfics, they always want to see their reader or subscriber comment all chapter that they updated. One more thing, they really work hard to write all chapters (long/short chapter) for readers to read. As i'm reader why i can't comment & vote fanfics that i love / subscribed. I think All author are really happy when they see their story have a lot of comment & upvote. Why some author didn't finish their fanfics? Cuz when they update story, their reader didn't comment. So they think that their story didn't have reader to read anymore. So they stop update fanfics. If u take author mind keep in ur mind, how do u feel? When didn't have any comment in ur story. I hate silent reader. I'm not good at english. Sorry :))
