If you are in something on Loop and you want it gone, ask and it comes down. You do not need a Loop account, and you do not need to know anyone here.
You do not have to explain yourself or accuse anyone of anything. Wanting a video or photo of yourself taken down is reason enough. We hide it as soon as this form arrives, before a person has even read it, and then a person checks.
Loop is a small site. This goes to the person who runs it, and to nobody else. If you cannot find the link, send the form anyway with whatever you remember — an unclear request still reaches a human.
