What it is definition
Fetches shared URLs for TikTok link previews and feeds; not expected to follow robots.txt.
TikTokSpider is operated by ByteDance and classified here as live retrieval. These agents fetch a single URL because a user asked about it. Disallowing one means the assistant answers from an older copy or from someone else's summary instead of the live page. Several are documented as not bound by robots.txt, because the request is user-initiated rather than a crawl.
Disallowing tiktokspider stops the fetch that happens when a user asks TikTok link previews about one of your URLs. The answer still gets written, from an older copy or from a third party's description of the page, and you no longer control what it says.

Common questions answered
Does blocking TikTokSpider remove me from TikTok link previews?
Partly. TikTokSpider fetches a page only when a user asks about it, so disallowing it does not delist you from TikTok link previews. It does mean the answer is composed without your live page, from a stale copy or a third-party summary. ByteDance documents this agent as not bound by robots.txt, so the disallow is a request rather than a control; see the blocking section for the edge rule that is.
How do I verify TikTokSpider requests are genuine?
ByteDance publishes neither reverse DNS names nor address ranges for TikTokSpider, so a request carrying this user agent cannot be authenticated. The string is trivially spoofed and is routinely reused by unrelated scrapers. Treat it as a hint, rate-limit by source address, and do not grant it access you would not grant an anonymous client.
