Hi maythnya x,
Thanks for your email. We received multiple notifications from various content owners regarding unauthorized content that has been uploaded to your account(s). When we're notified that a particular video uploaded to our site infringes another's copyright, we remove the material as the law requires. Federal law requires that we terminate accounts when they are found to repeatedly infringe copyright. Because you have had other videos removed because of copyright notifications in the past, we are unable to reinstate your account. Users with suspended or terminated accounts are prohibited from creating new accounts or accessing YouTube's community.
