So... About the fanfiction.lol site that is being shared... I am someone that has a little web dev experience, have done several coding projects and am an IT professional. I did a minor investigation on this and here are my thoughts:
So what this is is a guy who I guess does front end dev work (think make websites pretty and maybe give them content) and wants to break out into full stack dev work (also add in the back end dev work which is about content hosting, user profile management, how the website is shared to the Internet etc).
This guy forks Ao3's code (which means he made a full copy of it, which is allowed based on the copyright Ao3 has) to then play at being a full stack dev without actually building any of the code or realistically most of the infrastructure. He is learning to do this from other people who also forked Ao3's code and regularly update their versions of Ao3 with the updates Ao3 puts out. Again, there is nothing legally wrong with that but yeah it's a scummy as fuck coding practice. All these sites are color overs of Ao3 with their own lil gimmicks and special takes. This site's is the 'no waiting' for sign ups and every tag is canon (which it already kinda is on Ao3 but just not wrangled).
Now here is the issue I see as an IT professional and coder myself
This guy admits he does not have full stack experience. This site is hosted on a private server he built himself as he is learning to do that, and he posted a guide for that too. My concern for this site isn't even AI scraping, it's your private data like passwords and email. Many people use the same password across many sites, and he doesn't have the background in full stack to provide top tier security on his site. He also hand built his server, again that is a security risk.
Also to consider, we don't know this guy at all. HE is a security risk. Are you wanting to share your email and password with him? His sever is going to host that information and he will have access to it. Do you trust him not to sell it?
This site's big gimmick is the no waiting for an account. My alarm bells are ringing that this is a perfect strike point for vulnerable data. He could be a genuine guy (and I am not claiming he isn't) and have all the fancy bells and whistles for security but I don't know that and right now our private information is the hot commodity every company wants to buy. He may have the best intentions but that doesn't matter to someone that is looking to strike for information. Post there if you want I won't stop you and I won't stop him from having this forked site, but I beg you, please use a unique password for this site for your own security. ((Honestly a really good practice in general too!)) I don't want anyone to get accounts broken into because of this.
TL:DR - I don't trust this. I don't care if I'm risking a loss if Ao3 collapses, I rather trust my personal data to a board of people that can keep each other in check and servers that have a track record for data security.
