Hi @Veridical, welcome to Scanlines and thanks for sharing your experience! You probably have already noticed, but just in case: we have a Peertube instance at videos.scanlines.xyz - you should feel free to upload there your videos. More details about our Peertube instance can be found here or in other threads tagged #peertube.
It’s unfortunate and surprising that your archive.org page got deleted! I really hope that was a glitch. We Pixelflowers also use archive.org and our feeling is that they’re somehow tolerant about copyright infringements, at least when those are part of a creative action…if you’re confident it was a glitch I’d suggest you to try again with them (even if you also upload to Peertube or somewhere else; redundancy is good).
