I download porn from bunkr and simpcity with CyberdropBunkrDownloader and from other websites like pornhub, spankbang, xvideos and xhamster with yt-dlp. I consume it locally using stashapp that has a deduplication tool and it also tags automatically the scenes that other people have tagged in stashdb, which is a crowdsourced metadata database similar to ThePornDB, Data18, IAFD and Indexxx.
