Hey there. When something is reported, it gets sent to the YT Policy Enforcement Team. Flagged channels are promptly reviewed to see if they violate our rules & only removed if they do. Dedicated YouTube staff are available 24 hours a day, seven days a week to review complaints.
You can always report a channel/video that violates our Community Guidelines by reporting it for review here: https://goo.gl/YpT4Ae . You can select the option 'Spam and scams' to report. Thanks for keeping YouTube safe.
