[bug] meta/robots has noindex, nofollow when account marked as discoverable

[amiskelly]

Describe the bug with a clear and concise description of what the bug is.

Individual post/status pages have the following meta/robots rules despite the account being marked as "discoverable" on the settings page.

<meta name="robots" content="noindex, nofollow">

The nofollow rule is also set on the account page.

If folks wish for their account to be discoverable by search engines, I think:

• status pages should be indexable
• the "show older" link on the account page should be able to be followed (so that the post history is discoverable)
