Is a phone farm worth it for faceless channels?

No, it is not worth setting up a phone farm for faceless channels if the goal is to artificially boost views, likes, or monetization. YouTube explicitly bans fake engagement and invalid traffic, and significant violations can lead to demonetization, account suspension, or permanent disabling of AdSense for YouTube.

Why it’s a bad bet​

Phone farms are designed to simulate fake user activity, which falls under YouTube’s invalid traffic and fake engagement rules. YouTube says invalid traffic can cause views and earnings to be removed, payments to be adjusted or withheld, and in serious cases the account to be disabled. That means the short-term numbers usually do not translate into real, lasting revenue

Depends how many channels we're talking about. Feels like overkill for just a few

If you want to make a phone farm, go with iPhones with real sim cards in them. It may be expensive, but worth it overtime. Can go with older models. Androids much lower quality for farming accounts.

if you use good iPhone infra it can work.

if it can help in promotion then why not.
If it requires big investment you may have to think.

its really not worth it
