Does Beshine still do custom videos and respond on Onlyfans?
I don't belong there at OnlyFans, but Bombayduk definitely does, so I'm sure he'll respond to you. 
To the best of my knowledge, Beshine does not offer custom videos. People ask, even suggest, but I have not seen any evidence that she does. Everyone should realize that the picture she posts today may have been taken a couple months ago, so making a video isn't as if the circumstances haven't changed.
I think it was over a year ago, Sol, that you remarked how pictures seldom got 100 views, indicative of less BEA participation. For a couple months, I checked and found that many, if not most, did get 100 views by the 30 day mark. Well, I decided to check again and see if this was still true.
To find a picture with 100 views, we now have to go back months. In fact, since last January, there have been only a couple hit that mark, ironically, one was a morph, that have always drawn less clicks than real pictures. Captain, AD, CB, and the user gallery guys you regularly cite do fine work, but the evidence suggests people like the real Beshine.
Interests change and alternatives have only expanded over the nearly 30 years since the BEA was founded, but one thing that you can always point to when assessing the demise of a site is the sniping and infighting, which causes people to walk away. I can point to this thread (and two others), where this went on for months on end, essentially by a single individual here, and see that "views" declined; a year ago, you might see 60-120 likes after 30 days, now it is more like 30-70. Does that seem about accurate to you? Have people sought alternatives that have less negativity? As for me, I wish to keep posting respectful of Beshine and others that share my interests, opining about aspects I find interesting, and hoping others join in the conversation.
When the 'check oil light' comes on, it is always best not to ignore it like Penny, but to check it out quickly to avoid damage.
