>>65246not a mod but you probably wont like this answer. From a coding perspective, its far easier to never have the ips expire. I dont know if thats what this board does. But usually, this would be a specific feature outside of a basic board functionality. ie. it probably doesnt expire.

Not a mod as well just a tech guy.
>How long does this website keep the IPs?
That depends on the web server configuration(NGINX or Apache or whatever they use). The moment you access the website it gets a HTTPS or HTTP server response logged into a log file, but after a while it goes away if you haven't visited the site in a while because of other people and scrappers and bots visiting the site. The log file gets filled and most likely restarts or it might keep the old log file for a while before automatically backing it up for a multitude or reasons. (Their configuration or maybe they need it for Law Enforcement if you post illegal content.) Also vichan and NPFChan are able to see your IPs if enabled. I've used NPFChan and it has the possibility of hashing your IP if enabled but who knows what the staff here has it configured.
>Do IPs also get deleted if you request a post removal?
No they do not. Just depends on their configuration. If they ban and remove all posts then maybe but who knows what other files they keep on you.
