uBlock Origin Lite works just fine.

EDIT: as I wrote here, I am quite confident that my YT account has already been “rolled out” because of the many ads in the last 5–7 days. Before, I had 1 or 2 before some videos; now there are also pop-ups. I have made some experiments with VPNs (Mullvad) and browsers in several fresh VMs. uBOL works differently than the standard uBO and, from what I’ve seen, it seems to work fine. I’ll just stop repeating that.

heh, youtube could do some fake accounts and spam them with help requests

STOP BLOCKING SPONSORS. LET THE SMALL CREATOR EARN THE LITTLE THAT THEY DO FROM AD REVENUE YOU THIEVES. FUCK THE PIRATES WITH A FLAMETHROWER UP THE ASS.
