Batch unhide posts

Yup. That’s what we did. Another admin did it because he misunderstood what it did.

@riking How about unlisting topics? Here’s my guess:

ActiveRecord::Base.exec_sql("UPDATE topics
SET hidden = false, hidden_reason_id = NULL, hidden_at = NULL
WHERE user_id = ?", User.find_by_username("fthzoob").id)
