Maybe they want you to correct your level of English skills. You have mistakenly set your skill level at "Fluent," within your Profile. Your post above shows that your skills are "Basic." Barely.
It looks like your account was suspended a while ago. Please, update your profile with more information about your skills and experience. In general, your overview should use complete sentences while clearly and accurately describing your skills and expertise. Make sure it doesn't contain any links with contact information. You may also want to update your profile with a picture that clearly shows your face.
