I write a little bit on fanfiction.net and was pondering getting a fictionpress account. My question is about receiving reviews. I've gotten quite a few reviews on my stories, but all some of them say are "Please update soon!" or "Really good, update soon!" or "When's the next chapter coming?" or "When is [plot point] going to happen?"
I usually have an Author's Note at the end of my chapters that explains a couple of things, like if there's something I wanted to mention that's not in the chapter or an explanation if I've been gone a long time. It usually consists of something like "Thank you for reading! [stuff I want to mention] If you have time, reviews an constructive criticism are always appreciated."
I'm considering adding a note that says something akin to "I've been getting a lot of messages like this lately, but please don't tell me to update or ask me when my next update is going to be. I'm in graduate school and I'm very busy right now, so my updates are going to be sporadic for awhile." (By sporadic I mean I post about once every eight or nine days.)
Would this come across as rude or condescending? It could be seen as me demanding that the courtesy gift of a review be tailored to my specifications. However, I'm honestly sick of logging on and seeing (literally) six reviews, all in a line, that say "Please update soon!" It kind of takes the enjoyment out of something I do for fun and in my spare time. I don't expect reviews, but I also don't like to be bombarded with demands for more content. Is there a polite way to say this, or if I said anything would it be automatically rude, sort of like preempting a Christmas gift with "And I want this, this or this, and definitely not that or that."
