Use Piped as a front end for y–t—. It's open source & non-tracking, but views still count. The creator is active on the fedi too.
Individual servers sometimes go off line or lose quality when they're rate limited. Just try a different server when that happens. If the one you're using at the time shows ads and there are too many, check preferences to turn them off.

i've only found k-drama communities on lemmy and it seems like they're all abandoned. i know several k-fanatics on mastodon, some hardcore c-drama folk and 3 other thai fans. i don't know if lemmy plays well with the more twitter-like parts of the fediverse but i can introduce you there if you have an account. i think we can DM on here?
