You can still see the site if you disable javascript. It's all there but there's that redirect on the first line of a script "dashboard.js". Looks like a quick edit.
Yeah, in my opinion that redirect is a shitty thing to do as it doesn't give a visitor an option to opt out of loading the reddit page. Redirecting someone to another domain is generally frowned upon.
I remember the data was not updated for some time... did he ever resume updating it after that? maybe the maintenance burden was weighing heavily on him?
No, jonpro didn't update after May 19, 2023 or so. I don't think he was happy dealing with a certain sub's mods when his last post was deleted/redacted.
I think because some subreddits was deleted and informations with shares from there was gone + user i think it's banned by IP, this is the reason why website doesn't work anymore
