A suspended account sees one full-screen notice at sign-in, "Your account is suspended", sometimes with a reason, and a note that our moderation team has emailed you the details. Check the email on your account, including spam.
You can appeal right there: write at least 30 characters, up to 2000, explaining your side. We read every appeal, and appeals are reviewed within 48 hours. The screen remembers that yours was received, even if you sign out and back in.
While suspended you cannot use EverConnected. To other souls you appear unavailable, with no reason disclosed to them.
