Instagram

Deleted content moves to Recently deleted and stays 30 days, stories get a day, conversations never come back. And full deletion takes up to 90 days.

The limits are named outright, and so is the list of what doesn't work with scheduled content: product tags, sponsored posts and collabs.

Hidden comments stay in the total count and their authors never learn. The filter is on by default, and it has nothing to do with the distribution of your posts.

Tagged content isn't shared with your followers, a collaborative post is. Plus the primary creator's rights: delete, go private or block — and the post is gone.

The platform has no such term: it has two bars and an “Account Status” screen stating whether your content is eligible to be recommended. Recommendations switch off for the whole account at once.

90 days for the account, two years for a story and a reel. Word-for-word definitions of views, viewers and initial views — and a list of metrics the Help Centre doesn't describe at all.

The list closes off posts, notes, reels and stories, but the Help Centre says nothing about distribution. The closeness prediction is computed from messages instead.

All six Meta system cards read end to end: not one signal about the hour of the day. What is there instead is five windows of time and three buckets of freshness, counted for the reader.

Three predictions out of ten are computed by the card separately for the first post of the session. Plus the mechanics of the carousel, the reordering of its cards and what the platform calls informative content.

Selection in the Explore tab goes in three stages, and among the ten predictions one counts the probability that you will tap “Not interested”. Plus two numbers: five seconds and 95 percent.

Recommendations have a system card of their own: ten predictions and thirty-one signals. One prediction is computed by a language model — that is what the document says. Plus windows from 12 hours to 84 days.

The platform calls borders, watermarks and crediting the author immaterial edits. Instead of percentages it offers a test in one phrase, and it counts the return to recommendations over 30 days.

At the start it's eligibility for recommendations and your angle that decide, not the number of videos. We break down what switches recommendations off entirely, how an angle differs from a topic, and which numbers to look at in the first weeks.

Paid subscriptions require a professional account with 10,000 followers and an age of 18 and over, and the availability list consists of 48 countries, with no CIS country among them. Plus withdrawal thresholds and payout dates.

The help centre describes the channel notification only for the first message. We go through how people get into a channel, what outsiders can see and why the launch happens once.
