Typical post from support staff linked below. If you have been continually flagged, you should submit the form linked in the post. I also reposted the link to the same form below. The topic posted above is helpful especially for checks to see why your account may be flagged. It also has a link to the form.
Since your account seems to have a permanent flag for the time being, you should probably just submit the form. Make sure you provide all the information requested.
