Not the worst idea in the world... Maybe accounts that have been inactive for 3 or more years should be allowed to post but they can't post links or crypto addresses for the first week they come back, or their next 10 posts or something. That way they can still contribute to discussion but not for financial purposes.

The amount of bought accounts in sig campaigns is kind of disheartening. Wish the managers would do a better job of checking account histories before allowing these accounts to join campaigns.
