What X’s report says

What it means

Post detected by automated systems as one that may contain spam.

Effect on visibility

Post hidden from recommendations to non-followers.

What X’s code adds

Dropped from For You for people who don’t follow you, and from the video feed. Followers still see it in Following (visibility-filtering/rules/tweet_rules.rs).
Common triggers in the code: engagement bait and engagement farming found by Grok’s review, gibberish posts, “fast reply spam”, and links that pass through a low-quality site.
The fast-reply-spam and gibberish versions expire after 30 days (abuse-enforcement-service rules).

Read from X’s open-source code. X’s live settings can differ.

What to do

“High recall” means the check is built to catch a lot, so it also catches some normal posts. One or two in a month is noise. If you see many, look for what they share: the same reply pasted under many posts, lots of @mentions or hashtags, or a link in every post.

Not the same as SpamHighRecall (account label). The report shows the two in different sections, so check which one you have.
