Edits and deletions

Edits

When you edit a post in Telegram, the bot receives the new version and the page is updated within seconds. The address of the post stays the same.

An edit made while the bot was not in the channel is not seen. For a public channel, the Import the history again button in the dashboard reads the channel again.

Deletions

Telegram doesn't tell bots when a post is deleted, so Bloggram has to ask about each post. How often it asks depends on how old the post is.

Posts younger than 24 hours: Checked every 5 minutes.
Posts up to 7 days old: Checked every 2 hours.
Older posts: Checked every 24 hours.

When a channel gets a new or edited post, its next check is brought forward to within 5 minutes. That means a recent post you delete is gone from the blog within minutes, while an old one can stay up for a day.

When Bloggram sees that a post is gone, its page is blanked, its photos are removed, and the address answers "Post removed".

How a check works

For a public channel, Bloggram asks Telegram's public page for the post. For a private channel, it uses the Edit messages of others permission. Only posts that arrived through the bot can be checked in a private channel. Unless the answer clearly says the post does not exist, the post is left alone. A timeout or an error doesn't count.

Two safeguards keep a mistake from wiping your blog. If a whole batch of posts looks deleted at once and none of them was seen alive, Bloggram ignores the batch, because the channel was probably renamed or made private. For public channels it also confirms that the channel name still points to the same channel before it removes anything.

Check now

The dashboard has a Check for deleted posts now button on each blog. It checks the posts right away instead of waiting for their turn. You have to wait 1 minute between presses on the same blog.

Hiding, editing and deleting from the dashboard

Hide: The post disappears from the front page, tag pages, the sitemap and the post count. Its address answers "Post removed". Use Show to bring it back.
Edit: Change the title and the text of a post. Titles take 1 to 200 characters and the text up to 20,000 characters. Saving here keeps plain text only: formatting, links and hashtags are dropped. If you edit the post in Telegram afterwards, that newer version replaces yours.
Delete post: Removes the post and its photos. You confirm by typing delete. It cannot be undone, and the post stays deleted even if you change it in Telegram later.

Photos are not edited in the dashboard. See The dashboard for the other screens.
