[FEATURE] Warn users prior to account suspension

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Accounts are getting suspended without prior warning and the content of the notification is extremely vague ("suspicious signals [indicate] a violation of our Usage Policy"). Very often, users violate the usage policy out of ignorance. The document is vague and its meaning shifts over time without any notice to end-users. An activity that is allowed one month is disallowed the next, but the document remains unchanged.

Proposed Solution

• Provide users with a minimum of 2 warnings prior to account suspension.
• Specify which aspect of the terms of use or usage policy the user is suspected of violating.
• Provide a reasonable way to appeal suspension.
• Provide an estimated time for a reply to appeals.
• Automatically restore suspended account after a month. Suspending a user for life is an extremely harsh punishment, and for software developers could be career-ending.
