It's amazing that you made a fan account for Debstheslytherinsnapefan, really it is. And had you not copy and pasted her work without her permission, it probably would have been the biggest complaint, but you did copy her work without consent and even by Wattpad's own rules you are plagiarizing.
Read the second bullet point in Wattpad's What is Copyright Infringement:
https://support.wattpad.com/hc/en-us/articles/216192503-Copyright-FAQ
What is a copyright infringement?
• Posting the copyrighted works of others without their legal consent
• Posting on behalf of an author and giving credit to them. This is still a violation of copyright and will be treated the same way. Consent is ALWAYS required from the author.
• Adaptations or slight alterations to a work, such as changing names, copying the events and writing them in your own words, changing character point of views, are a violation of copyright.
• Using an image that you do not own. This includes making a cover with an image that you do not own the rights to (unless it is in the public domain).
So please take this down before you cause Debs more stress over stealing her hard work
