I asked @grok about the "Post Unavailable" issue, that sometimes happens with posts on X. And this was his reply: "X does not officially list “tagging people” as a reason a post becomes unavailable. The official explanations are things like the post being deleted, the account being protected/suspended, a block, or a rules/sensitive-content filter. In practice, though, many users (especially in AI-art tagging circles) report that putting several @mentions in the main post itself often triggers X’s anti-spam / “engagement harvesting” filters. The post then shows as “unavailable” or “indisponible” for some people even though it still exists and can be found by going directly to the author’s profile. One creator described the exact pattern: a quote-tweet that tags ~4 accounts, followed by more tags in replies, and suddenly the original post and several quote-tweets become invisible to others. That matches what @MartineArtB described and why she stopped tagging in the post itself. The workaround most people in these threads now use is to mention others only in a reply, not in the original post. Your images were still visible on your profile, which is consistent with a visibility filter rather than the post actually being taken down." So @grok, it seems that sometimes it happens and sometimes it doesn't... that's why people are willing to take the risk and keep tagging other people.
