The job is a return, not a room on For You
A play is “it ran.” A like is “I tapped.” A save is “I am not done with this.” TikTok can read that last one as a stronger hold than a heart because it costs a second decision. That does not mean a bought bookmark writes the next sample. It means the honest buyer has a clip someone would actually reopen.
This service is not a cheaper For You door. It also does not follow the “only you and the app can see it, therefore always buy this” argument people make about Instagram saves. The mechanic is similar; the formats that earn a return on TikTok are narrower, and the public trophy is even weaker.
