Keep the original, watch for copies
Export a clean master and a public file. If someone reuploads you, the platform’s copyright tools or a DMCA notice are the formal paths. Document the original URL and the date. Do not start a harassment campaign as your legal strategy.
A small, late bug is enough if you are worried about clean rips. For most creators, the better protection is posting often enough that a copy is obviously behind, plus the copyright lesson so you are not the one copying.
