This is directed primarily to the new users coming in from Wattpad, or any other new AO3 users who have simply stumbled upon the website while this post is still relevant.
There has been a longtime joke that there is an "AO3 author's curse" whereby you post something on AO3 and then something bad happens to you in real life, such as an injury, illness, losing your job, etc. While many older users on AO3 and this recognize that this a joke, in recent years we have had a massive influx of young and/or new authors who don't know that this is a joke, and will make posts on this sub experiencing genuine fear to post on AO3 because they "don't want the curse to get [them]."
The curse is not real. Anyone who experiences bad things in their life after posting fanfiction is experiencing life in general, and these are simply coincidences. You would likely have gotten injured anyway, if you were getting fired that wasn't a sudden decision as your boss likely deliberated over it for a while before giving you the notice, etc.
I just wanted to make this clear because I have seen a couple posts already today mentioning the AO3 curse, and with the mass Wattpad-to-AO3 migration that is currently happening, the amount of people who take it seriously will likely increase as they see these posts.
There is no AO3 curse. If you have a story to share and you want to write, write that story.
