There's really no point in bumping and here is why I think why.
I've never subbed to Leobane's OF but I've subbed to a lot of others. When the content is good I immediately download it, wait till my sub expires and then share it. If the content is boring (ie. no nudity for non porn actors, or just dick/ass pics or jerking off videos for porn actors) I don't bother downloading it because to me it's honestly a waste of time, and I already wasted money on an OF that to me is not worth it. I think quite a few people share this thought process; when the content is good someone is bound to share it eventually.
In Leobane's case his OF has something of 550-600 media, and yet very little has been shared at all, which to me means that it's only pics in underwear with a dubious bulge, gym videos, and maybe some artistic nudes. All of which we've already seen for free on his IG stories at one point or another.
