Less danger than OPsec nerds hype up but enough of a concern you want at least a reverse proxy. The new FOSS replacement for cloudflare on the block is Anubis https://github.com/TecharoHQ/anubis, while Im not the biggest fan of seeing chibi anime funkopop girl thing wag its finger at me for a second or two as it test connection, I cannot deny the results seem effective enough that all the cool kids on the FOSS circle all are switching to it over cloudflare.
I just learned how to get my first website and domain and stuff setup locally this summer so theres some network admin stuff im still figuring out. I don’t have any complex scripting or php or whatever so all the bots that try scanning for admin pages are never going to hit anything it just pollutes the logs. People are all nuts about scraping bots in current year but when I was a kid allowing your sites to be indexed and crawled was what let people discover it through engines, I don’t care if botnets scan through my permissively licensed public writing.
IMO 4k resolution is overkill its way past the optimal between file storage and visual fidelity. Nobody has ever complained about the visual quality of my 720p or 1080p sourced stuff much in the same way most sane people wont notice the difference between FLAC and mp3 on average listening. Bhack in my day we were lucky to get 480p on a square box tv.
