Either way, my goal never was to "expose" anything, just give information. In that vein, speedvid is using 10x to 20x more cpu than a usual video player. Probably mining, i'd avoid that site for the health of your system.
I imagine these people are doing this for some kind of reason, probably ad monetization. Quite simply tonia is lying for more clicks, and matrilinear may have uploaded a corrupted file by accident (automation will do that).
