If you’ve convinced people to do it that’s cool and it obviously works for you and them. I’m not judging but I don’t think it’s right for the rest of us to try and get our friends to burp on a recording and upload it here without their consent. And personally even if i had it would feel weird posting it.
At least online, I’ve always had one or two people at any one time who will send me audio or video. I agree it’s more interesting than just looking at videos on youtube.
I have a few friends who often burp around me, but not really for me, although they know I don’t mind their burps or even find them entertaining so I’ve seen a lot of really good ones from them. At times I wish I could record some of them just for my own personal collection, but I could never get away with doing it without them noticing, which would be awkward. I would never post a video of any of them burping online though, that is totally unethical to me and really kinda creepy. It wouldn’t be that hard for any video posted on here or anywhere to end up somewhere like youtube and then for the friend to one day see it on there and be really hurt by it.
On the other hand I am happy to share any of my friends burps and my encounters with them involving burping on here but in the form of written stories, with their names changed. Of which I have shared a few. I think that way is a lot more ethical as it’s anonymous and not likely to ever be seen by them or anyone outside this forum.
