One of the biggest nightmares for content creators and brands is unfair copyright strikes by malicious competitors or trolls. Sometimes a single strike can cause an account built over years of effort to be shut down in seconds.
DMCA and Counter-Notice
Because platforms are subject to United States laws (DMCA), they must immediately remove content upon receiving a copyright strike. However, this law also grants you a defense right. If you are certain the content belongs entirely to you, you can seek your rights by filing a Counter-Notice form.
Things to Pay Attention To
Even licensed music playing in the background is a sufficient reason for your post or account to be closed. Always use royalty-free music in your content. Reopening accounts closed due to copyright strikes is much harder than other types of closures.
