@Frellwit@lemmy.world is right, the following FAQ is from the uBO's YouTube Mega Thread on reddit.

How often should I manually update filter lists? Can I somehow automate this?

YouTube filters are in a list named uBlock filters - Quick fixes. The list updates every 12 hours. It's the only list you might need to update - only if this page says it's fixed, but you're getting the message.

If you're not getting detected. Don't update. Current estimated cost for just ONE of uBO's CDNs: HERE. This is with other lists updating every few days. uBO's not a company, it's a volunteer project using free services, which have limits that we cannot cross.
