I never had that problem with adblocking. It still works for me (Windows, Ublock, Firefox). The content on PeerTube isn’t on par with YouTube and there isn’t a financial incentive for the entertaining creators to move to PeerTube

Use a VPN if you want to be safe. slsk is p2p. If you don’t want to pay for a VPN, there’s a lot of ways to get music via DDL.
