Though I personally rarely used RARBG it sucks to see it go, but we still have scnlog, rutracker, CRR, torrminatorr, slsk, alvro/no-intro, old-games, predb, gamecopy/consolecopy, xatab, the-eye, dodi, myabandonware, gamesdrive, bt4g, kemono, tapochek, rlsbb, m2v, emuparadise (needs a specific userscript to function), private Discord/Telegram channels, sp00ky 1337 h4x0r tools...
.....ect.
What I'm trying to get at here is, yeah - RIP in peace RARBG - but, despite the hyperbole of the average Redditoid on the topic, piracy isn't even close to dying.
It's all out there somewhere and if you don't know about it then you just need to get the right people to point you in the right direction.
